8th visa run this year.

I’m visiting my gf since February. Always did visa runs. The last 2 times I got pulled aside and I had to provide pictures and they also called her. Today I exited via Shenzhen and they called a supervisor and asked me the same question. They didn’t give me an exit stamp this time. He asked when I come back and I said tomorrow. This definitely gonna be my last visa run for this year. They might refuse my entry tomorrow
