Dear Maintainer,

A message catalog for Chinese is installed in
/usr/share/locale/zh/LC_MESSAGES/giac.mo .
This catalog is thus seen both by users in the People's Republic of China (locale zh_CN) and in Taiwan (locale zh_TW).
But the script used in these two countries is different (Simplified Chinese characters in zh_CN, Traditional Chinese characters in zh_TW), and due to decades-old political reasons, it is culturally inacceptable to present messages in Simplified Chinese to users in Taiwan.

The file should therefore be be moved:
/usr/share/locale/zh/LC_MESSAGES/giac.mo -> /usr/share/locale/zh_CN/LC_MESSAGES/giac.mo
