In fact, the nine major classification societies under the International Maritime Organization, an international non-profit organization, have very good welfare benefits and are difficult to enter. Nine classification societies have offices in Shanghai, Jiangsu and Zhejiang, and few employees recruit materials every year. People recruit, you are better, you can win.
In addition, there are more foreign companies in Jiangsu and Zhejiang than small and medium-sized enterprises, and I believe it is not difficult to find them online.
The above is just a personal perspective, and more information needs to be found online.
