$ docker tag leimao/wechat:0.0.1 wechat:0.0.1

$ xhost +
$ docker run \
    -it \
    --rm \
    --ipc=host \
    -e DISPLAY=$DISPLAY \
    -e XMODIFIERS=@im=fcitx \
    -e QT_IM_MODULE=fcitx \
    -e GTK_IM_MODULE=fcitx \
    -v /tmp/.X11-unix:/tmp/.X11-unix:ro \

As of 1/15/2022, this Docker WeChat still works fine.

The WeChat in other Docker WeChat is usually emulated with Wine, whereas the WeChat in this Docker WeChat is build natively on Linux. The advantages of this Docker WeChat compared to the Wine emulated WeChat is that this Docker WeChat has fewer dependencies and the configuration is much easier.

Other Wine based Docker WeChat does not have the issue with fcitx input methods. However, fcitx input methods does not work for Docker WeChat, preventing the user from entering Chinese. Please contribute if you know the solution to this issue.
