shang hai » shang kai, dang hai, chang ha
tan chia » than china, can china, dan china
tan yong » tan hong, tan kong, tan yang

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: twinn ian ((tuan vu) OR (((tan chia) OR (tuan china)))) tan yong li shang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "twinn ian ((tuan vu) or (((tan chia) OR (tuan china)))) tan yong li shang hai ;~".
• Adding a wildcard symbol may retrieve word variants: twinn ian ((tuan vu) or (((tan chia) OR (tuan china)))) tan yong li shang hai ;*.
