is there any places that we can hold welfare activities for muslims there in guangzhou?

Hi. I want to know if there is a place in GZ that I can hold welfare activities for muslim there. My friends and I are planning to visit the city for our international visit program. So, I would appreciate it very much if you can recommend me any mosques, islamic centres & muslim schools in GZ that we can hold charitable activities for them at least for 3 days. Thank You.
