EggWaffle: Thanks for your advise. However, it is quite challenging for some people to leave their home/family/current job to teach English while learning Chinese in other country.
This service is to provide people a channel to speak Chinese with native Chinese speakers anywhere they want. Besides becoming more confident in speaking Chinese, this service can also help them to make friend with native Chinese speakers so that they can have a local tour guide if they want to travel to the place where they live.
