My wife's current passport visa in Vietnam has expired for several years. Will she be sent back by the police?

If found by China Public Security Bureau, they will be sent back and may face a large fine. I am from Wenzhou, and there is a man whose wife is also Vietnamese. Because her visa expired, she stayed in China for a few days, so she was fined 2000 yuan every day, which was huge. It is suggested that the landlord can take your wife to the Vietnamese Embassy in China for a new passport before leaving Chinese mainland. You can go to Hong Kong or Macau first, and then apply for a Chinese visa.
