First: Maybe Wulin Baby didn't sign a long-term cooperation agreement with Wulin Column Group;
Second: if the TV column group to which they belong does not stipulate that they cannot participate in other columns in their spare time, these beautiful women with placards can go to other TV columns to participate in activities;
Third, we often say that we have been poached by other TV stations with higher employment wages (job hopping).
I hope the above answers can help you.
