When did JIAOZHOU sign up for the transition class? What time does the class begin? Help!

I just went to see it the day before yesterday. It looks good. It is said that it is the first phase of 800 yuan with a group purchase price (5 people), which lasts for 4 weeks and has been registered. Including lunch, lunch break, etc. It's quite big and formal, similar to kindergarten. Do you want to go? Let's join a group. We are from the kindergarten of the Grain Bureau.
