Because there will be settings for synchronous calling and signature on the computer, the mobile phone does not support modification for the time being. If you set synchronization on your computer, your personalized signature will be synchronized with the conversation, but the conversation will not be synchronized with the signature.

Other reasons:

1, Tencent will send a notice to inform the system maintenance.

2. If it is not during system maintenance, then you need to open QQ and click on your personal information. Next to the personalized signature, there is a "Save personalized signature to space".

Personality signature:

Stay with me. I don't want to make you happy, but because I am.

2, the world of children, only children understand. Our time, only our memories.

3. When you love someone, you only see the advantages of the other person, but you don't care about the shortcomings.

Let's welcome the warm spring with open arms.

5. We didn't have a mobile phone, a computer or wifi before. At that time, we were happier than now.
