Thilo. I don't know your age, matrimonial status or educational qualification but if you are that keen why not get a job teaching English in China.
English is a compulsory subject in China and those wishing to continue their education overseas have to pass what is called TOEFL (Test of English as a Foreign Language). This is test of both grammar and conversation. To avoid their students learning what is known as Chinglish they employ foreign native English speakers in colleges to teach correct pronunciation, grammar and the differences between through and threw.
You have to get the qualification first and you can search that on the internet. You will have competition with university students on their gap year and if you are successful you may end up in the back of beyond with no western people or food in sight. If nothing else you will have to learn Mandarin to get around.
It's a suggestion. I know a few that do it including a Kiwi but I have lost contact with them.
