From the late 1980s to the early 1990s, the column "Window of Humor" of Harbin TV Station was hosted by Liu Liu and Shi Lei, and it featured a collection of humorous cross talk essays which were popular recently. It is broadcast once a week, around 8 pm, about half an hour, and only two or three sketches can be broadcast. Every time I read it, I feel that I have a short time and unfinished business. Other provinces don't understand. At that time, the audience in Heilongjiang Province could only go to the Central Committee 1 2 (there were no 3 or 4 at this time), Heilongjiang Satellite TV (it was not called Satellite TV at this time, but only this one in the province) and Harbin TV Station. The name of each station is different from what it is now. All TV stations don't broadcast programs all day and watch TV until it doesn't snow at the weekend-Lanxi audience.
