"19 Days" is an original comic by the cartoonist old in mainland China. It is a youth campus story featuring four teenagers. The popularity is very high. In 2016, it ranked first in the "China Super IP-TOP100 Influence" list. The comics probably started in 2013 and are still being updated. The details of the pictures are still conscientious. There is a beautiful and unique style of body painting, and occasionally cut the mirror very beautifully! The ratio rarely falls apart. Realistic background coloring is good. Breakpoint plot. Except for major events, they can basically switch to another scene at any time. I don't know if this is considered an artistic technique, but there are many fans of this comic, so there are no complaints in the comments. In addition, because the update process is too long, I once thought that this plot was a positive narrative, but I didn't realize it was a flashback until one day later. In fact, the characters are not too brilliant. At present, the labels and personalities of the two male protagonists are very good. Seeing one is a boy who has a delicate story and will cry secretly, Zhan Zhengxi is an upright person, three-dimensional is still three-dimensional. The emotional drama of the two shows that the author is careful. But they didn't jump out of the routine. Zhan Zhengxi and Zhan Waixi didn't matter to me.
