What procedures do I need to go through if I want to live and work in Estonia?

One of the immigrants who went to Estonia was an investment immigrant in the name of doing business, about 600,000 RMB, and needed relevant certificates from a domestic bank. There are also work visas for marriage immigrants, Estonian citizens and people employed by Estonian companies and sponsored by employers. Another risky way is to travel to Estonia and then stay to apply for refugee status. However, this is rare because China has friendly relations with Estonia and it is unlikely to grant refugee status. Generally speaking, investment immigration is preferable.
