The advantage is that the boss will give you about the same salary as you do. Year-end awards and tourism bosses will be held vigorously. Moreover, food and accommodation are good, and many factories can't satisfy them. Boss Liu is more humane in this respect.
The disadvantage is that employees are tired, because his business is good, natural employees work overtime, and the whole person and mind are very tired. In addition, in order to meet the ICTI standard, all parties should cooperate.
As an employee, getting the most salary is a trivial matter, but the boss wants to do the most with the least money. So it depends on whether you rely on money or health. But not just money. You must leave the factory when you feel too tired.
