Mailing Center and Expansion

The Mailing Center is where you manage the postcards you've sent and received. If you run out of parcel slots, you can add more in the Expansion Center.

Where to find it

Bottom PC tab → Outbox (「寄件箱」) or Inbox (「收件箱」) on the home page.

Steps

  1. The top of the Mailing Center (「邮寄中心」) has two tabs: Outbox and Inbox. The Outbox lists the postcards you've sent that are still on the way, each showing its number, the recipient, the start and end provinces, and the number of days it has traveled. A red dot on the Inbox tab means there are new postcards you can register.

  2. Your Mailbag (「邮包」, parcel slots) decides how many postcards you can have out at once. "Mailbag 0 / 6" (「邮包 0 / 6」) is your current usage and your limit. Tap the ⓘ next to it to see the rules, and tap Expand (「扩充」) to go to the Expansion Center.

  3. The magnifier at the top right is for search. You can search by POSTID, username or destination city.

  4. The first step of Send Card (「我要寄片」) is Choose a Recipient (「挑选收件人」). The system recommends a batch of people from the candidate pen pals. Each card shows the pen name, pen number, location, PC bio, distance and when they were last online. Tap one to continue sending.

  5. If there are too many candidates, tap the filter at the top right to filter by credit score, gender, age group, zodiac sign or province. After you set your filters, tap Apply filters (「确认筛选」), or tap Reset (「重置」) to restore the defaults.

  6. In the Expansion Center (「扩容中心」), you can use coins to add Mailbag slots and Postcard Vouchers (「收片券」, receive-postcard vouchers), or get PC+ for higher limits. This guide only goes as far as the confirmation page. Before you tap Redeem (「兑换」), check the quantity and price.

Result

After you expand, your Mailbag limit and voucher count go up right away, so you can send more postcards at the same time.
