Why do you always post jokes about whether you know the fireworks?

Every time I post a joke, I wonder if it’s because of the fireworks.

The shooting of street scenes in "Knowledge" is still very pyrotechnic and very stylish. The control of the color tone makes people look warm and comfortable. The overall tone of "Knowledge" tends to be gray, which was also the main tone in the Song Dynasty. It was unobtrusive and restrained. The crew also restored some activities that would appear in the market, such as lanterns and craftsmen.
