How long did you stay illegally in Thailand?

Illegal immigrants will be dealt with according to your specific situation.

In this case, I suggest you go to the China Embassy to get an exit certificate and pay a fine. The embassy lawyer will be responsible for seeing you off. However, it will take about 2-3 months to get it at the embassy in China.

Or you can entrust a powerful local travel agency in Thailand to send you out. You must also pay a fine, and they should also go to the China Embassy to get your exit certificate.

You can't do it yourself. Don't take the risk. I will definitely detain you. Lock you up first, then you will need more money. ...

This is how illegal entry is solved all over the world. Countries like Thailand can spend money, but not Europe, America and Singapore. You have to be sentenced first. After you are sent back to China, China will punish you again with a fine of about 5,000 RMB. After that, your passport will be confiscated and you can never go out again.
