There are several shipyards, the largest of which is Xingang Shipyard of Tianjin Xingang Shipbuilding Industry Co., Ltd. under CSIC. In addition to Xingang Shipyard, there are Xinhe Shipyard and CCCC Bomaike. The scale of the latter two companies is ok, but Xinhe Shipyard is basically a private enterprise with private ownership accounting for 52%. As for the treatment, it won't be very high. The shipping market is not good now. Among the three companies, the best treatment is China Communications Bomaike, but it is not much better. The largest is the harbor boat, and the last is the river boat. It is not difficult for college students to enter Hong Kong this year, and others don't know much about it.
