Questions & Answers about zhīfùmìmǎ bùnéng gěi kèfú.

Why is 支付密码 at the beginning of the sentence?

This sentence uses topic-first structure, which is very common in Chinese.

• 支付密码 = payment password
• Then the sentence comments on that topic: 不能给客服 = must not be given to customer service

So the structure is roughly:

• 支付密码 → as for the payment password
• 不能给客服 → you must not give it to customer service

A very literal English-style breakdown would be:

• The payment password, [you] cannot give [it] to customer service.

Chinese often puts the important thing first and then says what should or should not happen to it.

Why is there no subject like 你?

Because Chinese often omits the subject when it is obvious from context.

Here, the full idea is something like:

• 你不能给客服支付密码。
• 你不能把支付密码给客服。

But in warnings, notices, and app messages, Chinese often drops words that are easy to infer. That makes the sentence shorter and more direct.

So 支付密码不能给客服 sounds like a brief warning such as something you might see in an app or security notice.
