1, SAIC-GM-Wuling (actually a joint venture between SAIC and GM), mainly engaged in vehicle business (classic Wuling van, Wuling Hong Guang, Baojun and other brands).
2. In addition to the above-mentioned vehicle business, the rest is now Wuling Industrial Company, which mainly supplies spare parts to SAIC-GM-Wuling (of course, there is also vehicle business, mainly in the field of special vehicles).
Then Yiling Company is a wholly-owned subsidiary of Wuling Industrial Company. Actually, it's a bit like a labor agency. Recruit people from Yiling to work in Wuling Industrial Company. It looks like the salary is the same, but the five insurances and one gold buckle are different.
Personally, if you can, just go directly to Wuling Industrial Company, otherwise why bother going around?
