I met a foreigner on my trip. The foreigner is very enthusiastic. He came from Algeria and added WeChat. After going back to chat, he asked for a video chat and praised me.

You can ask this question on Baidu, which proves that you have a secret crush and lack a support. As a man in China, I don't recommend having sex with strangers on the trip, because neither side knows each other, and this foreigner has not officially dated or chatted with you, so it is estimated that he just wants to have sex with you.

Besides, he is a foreigner and you don't know his family background. It's hard to say whether he has sexually transmitted diseases.
