1: The temporary solution is to restart a QQ after the problem solved, but this method is not good, because restart soon after will encounter QQ can not enter the reason for the Chinese, the next time you have to restart QQ
2: Netizens said to minimize the QQ and then maximize but I did not succeed in the test. Failed
3: Restore the system, this is before the system installed and patched and installed the program when the backup system (success).
4: Reinstall the Input method, or not the problem remains, and then I was reinstalled qq+ input method after the next day automatically good.

2. Then open the Butler we click on the software interface of "computer assistance" as shown.
3. Then enter the QQ in the search box can not enter Chinese, and then click to find a solution
4. In the solution found we clicked "Fix now" on the right and then restarted the computer to solve it.
