It seems that there are even more packages depending on each other.

Try the command

sudo dpkg --purge language-pack-gnome-zh-hans language-pack-gnome-zh-hans-base language-pack-zh-hans language-pack-zh-hans-base

While the previous answer would probably work, why not just use apt to do it rather than expanding the list by yourself?

  sudo apt purge language-pack-zh-hans-base

Can you help with this problem?
