What kind of company is Beijing Construction Engineering Huachuang Technology Development Co., Ltd.?

Private enterprises can be said to be large family enterprises. Low salary and low welfare. Huachuang used to be a high-speed rail, but now the high-speed rail is sluggish, so it has been changed. Many old employees have jumped ship. The company has a long history, iron-clad Huachuang and mobile employees. As for the running water employees, why should they leave?
