What does 除非……否则…… mean in this sentence?

It means unless..., otherwise...

So the structure is:

• 除非 + condition
• 否则 + result if that condition is not met

In this sentence:

• 除非身份证明和申请材料齐全 = Unless the identity documents and application materials are complete
• 否则不能提交 = otherwise, it cannot be submitted / you cannot submit it

This is a very common formal pattern in Chinese.

Why are both 除非 and 否则 used? Isn’t one of them enough?

Sometimes one is enough, but using both makes the logic extra clear.

• 除非 A，否则 B = Unless A, otherwise B

This is a standard paired structure in Chinese, especially in formal instructions, rules, and notices.

You could also hear:

• 除非身份证明和申请材料齐全，不能提交。

But 否则 makes the second clause sound more explicit and natural in formal writing.

Why is 齐全 placed after 身份证明和申请材料?
