What would motivate you most to teach in a summer school in China.
1) Learn about Chinese culture
2) Help people in a developing country, especially in smaller towns.
3) Earn money
4) Travel
5) Other please specify

if i were to teach in China my main motivation would be to help the Chinese learn and grow. here in the US i feel that sometimes we are too selfish and greedy, people go to china for themselves. i want to see a good relationship between America and China, so i would start by helping the Chinese people learn and grow.
while studying at my university (in the US) i have tutored many international students with their English, grammar, economics, conversation, anything... i do so at no cost because just interacting with them is fun and i learn so much. if i were to go to China my main priority would be exposing my students to new ideas and knowledge. helping them to make themselves smarter and better
in the end we are all the same, weather you are from America or China or anywhere. seeing people better themselves is something that makes me so happy. knowing that i helped them makes me even happier, so that is what i want to do

I am in China at present and for last two years. I teach too. Motivation is to help others, learn new skills and the people are always so nice. Always.

Culture, Travel, Different Enviroment, Income probably last; you won't get paid much unless you teach in a upscale school. But most peoples go to there teach is not because of money.
