1. Most colleges and universities have been decentralized to local governments by the end of this century. Without industry background, it is difficult for students to have a solid internship and practice because there is no active cooperation from enterprises in the industry. Unlike in the past, everyone belongs to the same system, and administrative intervention must seriously accept interns;

2, the enterprise is eager for quick success and instant benefit, hoping that students can use it, so students have to go to the training company for training first;

3. Colleges and universities have limited funds and are not allowed to charge extra fees, so they can't engage in fee-based training and can only hand it over to educational institutions in the market.

4. The government has the responsibility. These social relations need to be regulated by the government, like Germany.
