Volunteer opportunities in Tianjin

Hi everyone,

My Name is Jeanette and my Partner and I will relocate to Tianjin mid June.
I am German , but lived and worked as Financial Reporting Manager in London for the past 3 years.
As getting a work visa seems to be a bit tricky I will start studying Chinese language in September and I am therefore looking for some volunteer work to do in the interim.
Unfortunately I don't speak any Chinese yet, so the opportunity has to be in an international environment.

Do you maybe have any ideas , all areas really (environmental work, schools etc.?
Thanks and bests
Jeanette
