Most people want to work in a joint venture, where pay is higher and there is opportunity for travel and advancement. These jobs are only for the lucky and highly-qualified few. The next important consideration is to get a job in a large city. In China living conditions are usually much better in the city. Once you get stuck in a small city or in the countryside, you may be stuck there for a long time.
Personal connections are quite important in finding a job.
Those who have influential family members or friends have a much easier time in finding a good job. Those who lack connections are often out of luck. If you've read much about China, you know that this is true for most things in Chinese society. There's also a lot of discrimination on the basis of gender. Women have a much harder time finding a job.
