Perhaps you should try some spelling variations:
than china » tuan china, han china, wuhan china
long lags » long ago, long days, long last
lags than » large than, less than, late than
tan yang » dan yang, tan yong, tao yang
tan ying » fan ying, ran ying, tan yong
die tong » die tone, die totung, die tanf
tong hui » wang hui

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "long lags than china ((tan yang) OR (tan ying)) die tong hui ;~".
• Adding a wildcard symbol may retrieve word variants: long lags than china ((tan yang) OR (tan ying)) die tong hui ;*.
