chatgpt-plus-pro-codex-cn-guide: a Chinese-language guide to buying ChatGPT Pro 5x and 20x without an overseas card

A documentation site for a payment problem, not a library you install

The repository has no package manifest, no build step and no test suite. Its top level holds index.html, app.js, styles.css, tokens.css, a _layouts directory, a docs directory, and static files such as robots.txt, sitemap.xml and llms.txt. The primary language is HTML and the published site lives at fangmumu111-bot.github.io/chatgpt-plus-pro-codex-cn-guide. The README is the product.

That matters for how you evaluate it. There is nothing to benchmark and nothing to run. The content answers a narrow question: how does someone in mainland China, without an overseas bank card, pay for a ChatGPT Pro tier that OpenAI prices at 100 or 200 US dollars per month. The README cites OpenAI's official article on Pro tiers for the plan facts, then spends most of its length on the practical route: check your own account page first, and only then consider a third-party service that accepts Alipay.

The intended reader is a Chinese-speaking individual user, often a Codex user, who has already hit Plus limits and is deciding between the 5x and 20x tiers. The repository is not aimed at teams, and the README says so directly: it warns against treating an individual Pro plan as a shared seat.

How the guide is structured: tier facts, three payment routes, then vendor

The README is organised as a sequence of decisions rather than as prose. It opens with the two official tiers, Pro 5x at 100 USD per month and Pro 20x at 200 USD per month, and states that both carry the same core Pro capabilities, with the difference being usage allowance relative to Plus: roughly 5x and roughly 20x. It adds the caveat that some models or features may carry separate limits and that the account page is authoritative.

It then lays out three purchase routes. Route one is the official ChatGPT web subscription through Settings then My Plan. Route two is in-app purchase through the App Store or Google Play, with the note that the store that took the original payment handles renewal, cancellation and refunds, and that you should confirm whether an old subscription is still renewing before switching channels to avoid a double charge. Route three is a domestic payment service that opens the plan on your own account.

The third route is where the repository stops being neutral. It names AIXiamo, gives RMB prices, links to product pages with UTM parameters, and supplies a QQ contact number for consultation. The docs directory carries the supporting pages: chatgpt-pro-cn-payment.md with a Pro availability section, a 5x versus 20x comparison page, and a separate page on GPT-6 Astra covering Codex CLI and the Responses API. DISCLOSURE.md is described in the README as containing the recommendation basis and evidence standard, which is the file to read if you want to know how the vendor was chosen.

Checking your own account before you pay anyone

The README's first instruction is also its best one: look at what your own account is actually offered before comparing third-party prices. The stated path is Settings, then My Plan, and the README says to read the Pro 5x and Pro 20x purchase and renewal options as your account currently displays them. If your account already supports a payment method you can use, the README says to subscribe directly.

There is no code in this repository, so there is no install command to run. The only executable-looking content is the site itself. If you want to read the source locally rather than through the published homepage, the repository is a static site, so a plain checkout is enough to inspect the HTML and the docs directory. There is no npm install, no build script and no dependency list in the repository, so any local preview is a matter of opening the files or serving the folder with whatever static server you already use.

The README gives one concrete verification step that is worth repeating because it is the only real acceptance test in the document: after the plan is opened, confirm the actual tier on your own ChatGPT account under Settings then My Plan. It states plainly that a third-party order screenshot is not proof of delivery. That single sentence is the most useful line in the repository.

The 5x versus 20x decision, and why the README tells you not to start at 20x

The comparison table sets out the official monthly prices, the usage allowance relative to Plus, and the intended audience. The README's own advice is to validate real workload on the cheaper tier first, and to consider 20x only when a single person is working all day across multiple repositories with dense long tasks. It also separates two situations that are easy to confuse: a new account or an account with no current membership, and an existing 20x subscriber whose plan is still active or still shows 20x after expiry. The first group is directed to the full recharge price, the second to the conditional renewal price.

The pricing as stated in the README, reviewed on 2026-09-14, is 719 RMB for Pro 5x, 1269 RMB for conditional Pro 20x renewal, and 1529 RMB for Pro 20x full recharge. The README says the vendor does not ask for a ChatGPT password, verification code, recovery code or session, and that payment is by Alipay, with WeChat Pay available if you contact support before paying. It also states the typical handling time as roughly two to five minutes, longer under peak load or account risk controls.

One structural weakness: the tier guidance is qualitative. The README says to watch whether limits repeatedly interrupt real delivery, and to check Codex Settings then Usage, but it does not publish a measurement method that would let you predict your own ceiling before paying. The 5x versus 20x page is described as containing usage estimates and three decision criteria, but the README does not reproduce them.

What the guide cannot tell you, and where it is the wrong tool

The central limitation is disclosed but easy to skim past. The repository recommends one vendor, links to that vendor with tracking parameters, and lists a QQ number for consultation and after-sales. The README points to DISCLOSURE.md for the recommendation basis and evidence standard, and it says the current RMB prices and handling scheme were reviewed on 2026-09-14, with live prices, stock, payment methods and delivery rules governed by the service page. Nothing in the repository shows an independent audit of that vendor, a refund track record, or a comparison against any other service. If you need a neutral review, this is the wrong document.

Second, the guide is explicitly not for API users. The README states that programs, servers or CI should use API keys through the separate API Platform, and that ChatGPT Pro does not cover API billing. Anyone looking to cut inference costs for an application will find nothing here.

Third, it is not for teams. The README warns against reading an individual Pro plan as a multi-person shared seat. Fourth, the failure path is only partly documented. The README gives a five-step check for a paid order that has not landed, covering the wrong account, unpaid order, manual processing state, a page refresh or re-login, and the plan display, and it says the vendor issues a full refund when a recharge fails and is verified. What it does not document is how long that refund takes beyond saying it depends on the original payment channel, the bank, or on-chain confirmation. There is no stated dispute process if the vendor disagrees about whether the recharge failed.

Alternatives, and the real difference in approach

The repository itself names two alternatives, and both differ from its recommended route in a way that matters.

The official web subscription is the first. You pay OpenAI directly, manage renewal and cancellation yourself, and there is no intermediary holding your order. The difference is not price but control and eligibility: it requires a payment method the checkout page accepts, which is precisely the constraint the repository was written around. If you have that method, the README's own instruction is to use it.

App Store or Google Play in-app purchase is the second. Here the difference is billing custody. The store that took the original payment handles subscription, renewal, cancellation and refunds, so a dispute goes to the store rather than to a vendor. The README's warning belongs to this route: confirm whether an old subscription is still renewing before switching channels, or you may be charged twice. It also notes that the 20x option available in-app depends on what the app displays for your account and store region, which is a real eligibility difference rather than a preference.

A third alternative is implied by the repository's own audience split: stay on Plus. The README states that for everyday chat, writing, study and occasional programming, Plus is often sufficient, and that the Pro tiers are for people whose limits repeatedly interrupt real work. That is a legitimate answer to the question the repository poses, and it costs nothing.

Maintenance, licensing, and what the MIT label does and does not cover

The repository is not archived, and the last push was on 2026-09-14, the same date the README records for its latest review of the Pro 20x recharge and renewal scheme. The README also carries dated technical updates, including a 2026-09-05 addition on GPT-6 Astra with a stated minimum Codex CLI version of 0.153.0 and a minimal gpt-6-astra request, and a 2026-09-09 addition on 5x versus 20x selection. The content is therefore being revised on a short cycle, which is what you would expect for a page tracking prices and vendor conditions.

That cadence is also the upgrade cost. Prices, tier availability and renewal conditions change, and the README defers to the service page for live values. A reader who bookmarks a price from this guide is reading a snapshot. The dated review lines are the signal to look for: if the most recent review date is far behind, treat the RMB figures as historical.

The licence is MIT, and the repository ships a LICENSE file. MIT covers the source of the site, meaning you may reuse and adapt the text and layout under its terms. It does not extend to the third-party service, its pricing, its refund practice or its delivery promises. Nothing here constitutes legal, tax or consumer-protection advice for cross-border payment, and the README's own position is that the service page governs the transaction. If you plan to reuse the content, keep the attribution and be aware that you are republishing commercial referral links.

Editorial conclusion

Adopt this repository as a reading list if you are in mainland China, have no usable overseas card, and want the tier comparison, the pre-purchase verification checklist and the post-payment troubleshooting steps in one place. Do not treat it as a neutral review: every payment route it recommends ends at AIXiamo, it publishes no independent evidence about that vendor, and the MIT licence covers the text rather than any promise about the service. Before paying anything, open Settings then My Plan on your own ChatGPT account, confirm which Pro tier your account is actually offered, and check the Pro availability table in docs/chatgpt-pro-cn-payment.md for the current renewal conditions, because the README states that the listed RMB prices were reviewed on 2026-09-14 and that live prices and stock are governed by the service page.
