tan yang » dan yang, tan ying, tan yong
zong hai » hong hai, dang hai, zong he

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: lang yan ((guan chia) OR (tuan china)) tan yang li ((zong hai) OR (long han)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan ((guan chia) or (tuan china)) tan yang li ((zong hai) OR (long han)) ;~".
• Adding a wildcard symbol may retrieve word variants: lang yan ((guan chia) or (tuan china)) tan yang li ((zong hai) OR (long han)) ;*.
