Package ibus-pinyin is now deprecated; its upstream has stopped development
for years in favour of new ibus-libpinyin. New ibus users should install
ibus-libpinyin instead of this package. This package (ibus-pinyin) will be
removed after Debian Buster (Debian 10) release.
@Ping-Wu: ibus-pinyin will soon be removed from the archive.
