Shenzhen I went to Shenzhen for an interview last Thursday. It was a 3-hour train trip. The interview was on Friday morning. After the interview, I went around Shenzhen city by taking subway. I had gone to the biggest electronic market in Southern China. This was the third time I went to Shenzhen. The first and second time happened ten years ago. And I never went to Shenzhen on summer. It was extremely hot when I was in there last week.
