Reference blog

https://blog.csdn.net/linux_2016/article/details/52356576
There is no execution permission to modify the library in the blog

Solution

Install: fcitx-frontend-qt5

sudo apt-get install fcitx-frontend-qt5  

Copy the dynamic library to two directories under the Qt installation directory

cp /usr/lib/x86_64-linux-gnu/qt5/plugins/platforminputcontexts/libfcitxplatforminputcontextplugin.so  \
/home/laoer/Qt5.10.0/5.10.0/gcc_64/plugins/platforminputcontexts
cp /usr/lib/x86_64-linux-gnu/qt5/plugins/platforminputcontexts/libfcitxplatforminputcontextplugin.so  \
/home/laoer/Qt5.10.0/Tools/QtCreator/lib/Qt/plugins/platforminputcontexts 

Add library executable permission

chmod +x /home/laoer/Qt5.10.0/5.10.0/gcc_64/plugins/platforminputcontexts/libfcitxplatforminputcontextplugin.so 
chmod +x /home/laoer/Qt5.10.0/Tools/QtCreator/lib/Qt/plugins/platforminputcontexts/libfcitxplatforminputcontextplugin.so

Then restart the computer, qtcreator can input Chinese.
