Perhaps you should try some spelling variations:
tran thanh » ban thanh, van thanh, quan thanh
dang trong » dung trong, dong trong, lang trong
tien manh » tien anh, tien thanh, tran manh
trong dan » trong dang, trong san, trong tan
anh tang » anh bang, anh dang, anh nang
tang cua » mang cua, hang cua, tang luan
cua dang » cua cong, cua ban
dan than » dan chan, ban than, van than
than man » than ma, thanh san, tran manh

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: hoc ((((tien manh) OR (tran thanh))) OR (tieng anh)) - anh tang cua dang trong dan than man~.
• Adding a wildcard symbol may retrieve word variants: hoc ((((tien manh) or (tran thanh))) or (tieng anh)) - anh tang cua dang trong dan than man*.
