Lubuntu 16.04 --- The Fcitx-Chewing input method cannot show the Chinese fonts.

Due to the Lutuntu 16.04 install process select the Englisht language, my system language is in English by default. If want to install the additional language as Chinese character, we need to launch "Language Support" item as follows:

At first, the keyboard input method switch to the "fcitx" mode based on the personal behavior.

When click "Install / Remove languages ..." button, we can select the prefer language as "Chinese Traditional" to be installed.

Note:
If the language support is trigger in the first time, the system will directly tell us that the language support is not installed completely and ask us whether want to install them now.

After install and reboot, we will choose the right language next to log on the system.

In the moment, the system will ask us whether will change the language of the profile folder to the current "new" language? By you decide!

To click the Penguin icon for configuring "fcitx" input method.

Add "Fcitx-Chewing" to the current input method.

When switch to Fcitx-Chewing mode and want to key in Chinese font by document editor, we find out the input screen is blank and cannot show any words.

By searching the Google, we find out maybe kill "fcitx-qimpanel" process can resolve this problem. It it is true by doing "killall fcitx-qimpanel" command next to key in the Chinese font again, we will disable "fcitx-qimpanel" fucntion when the system boot by doing the following process.

Reboot and log on again for verify whether the problem can be resolved.

If the problem still exist, maybe need to install the "Qt Quick" module

Reboot again and almost the blank screen will be resolved.
