Avantages
Work at home tutoring Chinese students in English literature or other subjects at about middle or high school level.
The students are very nice.
It does take, on average, 30 to 60 minutes to prepare for the tutoring session.
Not a pro or a con, but this is set up to be a part-time job for college students, so there are no "career opportunities."
Inconvénients
If you are a night-owl: US time changes, China's doesn't. That means in the winter, one has to work before dawn.
If you are a morning person, this might be a pro.
