What is the significance of the colorful cloth on the left chest of the new uniform of the Chinese Army?

It is a rank seniority badge, which is used to indicate the rank and service life of officers, including the first-level company, the second-level battalion, the third-level regiment and the fourth-level division. The one in the middle of the first floor is a grade chapter, decorated with metal five-pointed stars, which distinguishes grades by color and number of stars. Yellow is the platoon leader, light blue is the company commander, dark blue is the battalion commander, purple is the head, red is the teacher, and so on. One star represents the deputy, and two stars represent the principal. For example, a purple star is the deputy regiment level, and two light blue stars are the joint posts.

The colored bars with vertical bars around the military rank brief are called service years brief, which are used to indicate the service years of officers, including one year, two years, three years, four years, five years, ten years and medal brief (white), in which the last added number indicates the service years of officers through permutation and combination.

For example, my grade seniority stamp, the first floor stamp and the middle grade stamp are light blue with two stars, and the fixed number of years stamps on both sides are three-year stamp and five-year stamp, which means that I am a regular employee and length of military service has been working for 8 years:)
