I found something you don't know: Wu is the vice principal of Yangming Central Primary School in Wuxi, Jiangsu Province, and teaches Chinese in Class 0/KLOC-0, Grade 5.

You know that this school was visited by our great old Hu classmate, so there is little detailed information on the Internet.

If you have a strong relationship, you can get what you want from Wuxi Education Bureau.

If not, you should spend some energy to get it from those primary school students slowly.
