What is the relationship between Zhilian Cai Yi and Zhilian Recruitment?

They are two completely different companies.

As far as I know, Zhilian Cai Yi initially recruited a subordinate department of Zhilian, and later threw it out to set up a separate company. Up to now, the two companies have embarked on different development paths.

Zhilian Recruitment is mainly engaged in recruitment, assisting some offline recruitment and talent evaluation products. Zhilian Cai Yi prefers human resource outsourcing.
