Perhaps you should try some spelling variations:
hanh trung » thanh trung, hanh trang, manh trung
trong dang » truong dang, trong dan, trong dong
dang thanh » dong thanh, dang hanh, hoang thanh
tran dung » tran hung, tran quang, trung dung
tran dang » tran quang, tran hoang, tranh hang
thanh cau » thanh chau, thanh mau, nhanh cau
kha nang » phap nang, ky nang, ki nang

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: ho ((chuc nang) OR (kha nang)) - hanh trung ((tran dung) OR (tran dang)) trong dang thanh cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chuc nang) or (kha nang)) - hanh trung ((tran dung) OR (tran dang)) trong dang thanh cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chuc nang) or (kha nang)) - hanh trung ((tran dung) OR (tran dang)) trong dang thanh cau*.
