Give online courses for Chinese, Math, or Physics. I was teaching at UMASS for 2 years for Chemistry courses

Yuan was my Teaching Assistant in a chemistry class when I was undergrad student and that's how I know her. She is knowledgeable and patient every time I asked her questions. One of the best TA I ever had.

Yuan was a math tutor when she was a grad student and I was one of her students. She is extremely patient and she could always explain in a very simple way so that her student who has a relatively weak background in math could still understand the problem or the concept.
