How many underground stations are there?

The "underground traffic station" has two parts.

The sitcom Underground Traffic Station was shot in two parts, the first was shot in 2007, and the second was shot on 20 10. This is a sitcom with the theme of anti-Japanese. The story tells a wonderful story that our Eighth Route Army intelligence officer launched an underground traffic station in Dingxiang Building, a donkey meat restaurant in Anqiu City, Hebei Province, to collect Japanese intelligence and attack the Japanese army. The content is novel and the lines are humorous.
