Evening.
My name is Paul, South African national. I have an HSK5, as well as having lived in Beijing for two years, working in a Chinese owned Biomedical company, then working for the national power grid doing training work, finally returning to South Africa to do volunteer work with the local Chinese community. I continue with the same volunteer work in South Korea presently.
I have also taught basic Chinese.
I am very confident I can help you.
I will require more details on the scale of the work however.
