Is it better to invest in Shanxi or to build it once in Shanxi?

As soon as Shanxi is built. According to Ikey's query, I learned that:

1. The office atmosphere of Shanxi No.1 Construction Company is relaxed, the environment is clean and tidy, and employees can comfortably complete tasks every day. Shanxi Jiantou Company has a poor environment and no sense of atmosphere in its work.

2. Employees of Shanxi No.1 Construction Company can get a monthly salary of 6,000 yuan and a year-end bonus of 1000 yuan during the New Year. The salary of Shanxi Jiantou Company is 6000 yuan, and there is no bonus for the New Year.
