College refers to higher vocational education, which is an integral part of higher education and one of the levels of university education. In China, professional education is undertaken by higher vocational colleges and junior colleges, and some undergraduate colleges offer professional courses at the same time. College diploma level does not issue a degree certificate, but an ordinary college diploma. College education is mainly divided into full-time colleges and part-time colleges.

Ear plucking refers to ear plucking, which originated from the people. Folk ear-pulling tools are relatively simple, and they are generally based on local materials. Bamboo sticks and thin sticks are simple ear plucking tools. Ear pulling originated from hairdressers, who invented professional ear pulling tools and professional operation methods.

Ear digging was popular in ancient Sichuan and developed areas of Sichuan. The more social status a group has, the easier it is to appear lacking under great work pressure, and only the powerful can enjoy it. With the continuous development of society, there has been a substantial breakthrough in both technical extension and emerging fields. Especially in the late Ming and early Qing dynasties, ear-digging began to flow into the people and integrate into the traditional hairdressing industry. It has not been forgotten in the years of war, but has been preserved and developed. This skilled ear plucking master used to be a must-have item in the court, serving the princes and ministers all the year round. At this point, ear picking has become a great enjoyment of life. Now the streets and alleys of Chongqing and Chengdu are everywhere.

To sum up, it would be better if the ear plucking is done with a college diploma!
