Chengdu women's Serbian tourism lost contact, and local Chinese said that people are still alive. What happened?

Recently, the disappearance of Ms. Zheng in Chengdu, Serbia has made further progress. The local Chinese in Serbia said that they had met Ms. Zheng, but Ms. Zheng's mental state seemed strange at that time, always talking to herself and not communicating with others. In addition, some local people took photos, indicating that Ms. Zheng is still in Serbia, and there is no accident. I just don't know why she doesn't contact her family.

First of all, Ms. Zheng went to Serbia six months before the outbreak. She keeps in touch with her parents. Later, when preparing to return to China, she encountered an epidemic and failed to return to China, so Ms. Zheng stayed in Serbia for another year. Results At the end of August of 20021,Ms. Zheng's parents and friends could not contact Ms. Zheng, so they called the police. Now, nearly a month has passed, and some social media of Ms. Zheng are still updated, but the content is messy. No one knows what Ms. Zheng meant by sending these.

Secondly, Ms. Zheng's parents have contacted the Serbian Embassy, which has also dealt with the police. At present, the police are still trying to find people. According to the local Chinese in Serbia, Ms. Zheng occasionally appears on the streets of Serbia, but she doesn't communicate with people at all. She just talked to herself when she left alone, so the China people who met Ms. Zheng didn't talk to Ms. Zheng. These news also show that Ms. Zheng is still alive.

Finally, the Serbian police sent some photos to Ms. Zheng's parents, and Ms. Zheng's parents were slightly relieved. But Ms. Zheng's whereabouts are still unknown, so why Ms. Zheng doesn't contact her family and friends is still a mystery. We can only solve the mystery after the police find Ms. Zheng, hoping that Ms. Zheng can return to the embrace of the motherland safely.
