How to cancel Zhihu by mail
Collect the details you need
You will need the name and email on the account and, if you have one, an account or customer number. Use exactly the details Zhihu holds, so the request can be matched to your account.
Draft the request
Postbye writes the letter in Chinese from our Chinese template, because Zhihu's address is in China. It opens with the subject line “主题：取消请求 – [your name]” and asks Zhihu to end the subscription, stop all further charges and confirm in writing.
Post the letter
Address the envelope to Zhihu, Beijing, exactly as printed in the next section. Certified mail gives you a tracking number and a delivery record.
Save the tracking record
Delivery confirmation is your evidence that Zhihu was asked. Watch the next statement or two for any further Zhihu charge.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Zhihu cancellation letter goes
Zhihu can be reached by post at 北京市海淀区学院路甲5号1幢三层1#厂房3-010, 100083 Beijing, China.
The envelope is going to Beijing, China, so the postcode 100083 must be on the front.
Your name, address and email appear in a short block labelled 账户持有人, 存档的账单地址 and 存档的电子邮件地址, under the greeting “相关负责人：”.
Prefer to write it yourself? Use our letter template
Before you cancel Zhihu, check these
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
- If an app store or phone carrier bills you, the company cannot cancel it. Cancel with that partner as well.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

How cancelling by mail works
A subscription ends when the company records your request, not when you stop using it, and a letter is the record you can show later.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
