How can I get rid of this language selection box in Win 10?

Hello guys, since i’ve upgraded to Win 10, this language selection box is following me wherever I type and is extremely annoying — It hides the word after my cursor and I constantly clicked on it by mistake. I would be really grateful if anyone could give me some hints on removing this.

For your information, I’ve installed both Chinese and English keyboard and thus the box keeps popping up and ask me if i want to select the other language.
