Printing a huge trademark on school uniforms, on the surface, not only makes money for school uniforms, but also treats students as "living advertisements", which can be described as killing two birds with one stone, but in fact this practice violates relevant laws and regulations. Manufacturers directly print huge trademarks on school uniforms without the consent of students, which actually damages the rights and interests of students and is suspected of violating the relevant provisions in the General Principles of Civil Law.
