Switching Between Languages

set english as main language。

alt shift to change to other languages。

but sometimes the chinese language turn up as main language and cannot be reset。

how to solve this？

i found a solution.

switch the language permanently to chinese and click the 英 button whenever i want to type english.

alt+shift

alt+shift

the alt shift function fails after sometime. maybe there's a glitch or something.
