Is there much foreign trade in Yantai?

There are many foreign companies in Yantai, mainly from South Korea. I studied and lived in Yantai for 7~8 years. I just came to Qingdao last year, only to find that Qingdao has more foreign trade. If you work, it is not difficult to find a job anywhere as long as you have a skill. Yantai's consumption level is relatively reasonable, and its living cost is relatively low. It is also a very good coastal city.
