What's the treatment of JAC pine air conditioning?

Jianghuai Automobile and Songzhi jointly set up a small company. Mainly responsible for supporting air conditioning equipment for Jianghuai. Songzhi is headquartered in Shanghai and its boss is from Hong Kong. JAC pine branch was formerly known as JAC Wandu, and later called JAC Mo Ding. Later, the boss in Hong Kong bought the equity of another partner, which is now called JAC Songzhi. The treatment in Hefei is ok. One of their technical managers is about 3,500 yuan a month, which is not bad in Hefei. But the welfare is not as good as JAC. The provident fund is very small. The year-end bonus at the end of the year is much less than JAC.
