Why does Huatian Technology often recruit people?

The reason why this enterprise often recruits people is because of its high mobility.

Huatian Technology sells many products around the Spring Festival and at the beginning of summer vacation every year. Factories recruit a large number of people, and factories with small demand begin to lay off employees, which leads to the frequent recruitment of Huatian Technology.

Huatian Technology is a company whose main business is integrated circuit packaging and testing.
