Questions & Answers about jiěguà yǐhòu, qǐng bǎocún jiāoyìpíngzhèng, zài kàn yínhángkǎ de yǒuxiàoqī.

Why is there no subject in this sentence? Who is doing the actions?

The subject is omitted because it is understood from context.

In Chinese, it is very common to leave out you, I, we, etc. when they are obvious. In a bank instruction like this, the implied subject is usually you.

So the sentence is understood as:

After unblocking/canceling the hold, please keep the transaction receipt, then check the bank card’s expiration date.

Chinese often sounds more natural this way than if it explicitly said 你.

How does 以后 work in 解挂以后?

以后 means after or afterwards.

When it follows a verb or verb phrase, it creates a time phrase:

• 解挂以后 = after unblocking / after removing the hold

So the structure is:

Verb phrase + 以后 = after doing ...

Examples:

• 吃饭以后 = after eating
• 下班以后 = after getting off work
• 付款以后 = after paying

Here, 解挂以后 sets the time for the rest of the sentence.

Why is 请 used here?
