Zuo Hang sandbags are made of this material.

Hello, this is not material, Zuo Hang is a personal name. Most of Zuo Hang's photos in Bashu were made public by teachers. Artists in the peak period can be called free spokespersons for activities as long as they are in Bashu. They can be seen in promotional videos, school celebrations and various shooting, and everyone will generally cooperate, because this is also a glorious thing. Zuo Hang was elected by the student union and became a member of the cultural and sports department. The teacher also took photos of his classmates in class. In the teacher's shot, Zuo Hang was recognized by fans with only one back. His popularity is too high. All the boys in the school have short hair. Just because he is a trainee, he needs to keep the shape of the pot cover, and there is a lot of hair in the back of his head. If you look at him carefully, there are women sitting at the same table on both sides. Zuo Hang sat up straight, and the fans were a little jealous, and then they were relieved.
