Which construction site in Xi 'an recruits college students?

If you contact a construction enterprise for internship (such as Zhongtian, Guangsha, Jiangdu, China Railway, Zhonghaitong, Shaanxi Construction Group, etc.). ), I'm sure I can go to the construction site, and there are internship fees. And there will be no students on the construction site. Maybe you can be a migrant worker. It may be very hard.
