Perhaps you should try some spelling variations:
thanh trung » thanh tung
chieu tinh » trieu tinh, lieu tinh, chau tinh
ho chieu » theo chieu, hoc thieu, doi chieu
tam dung » tam duong, tan dung, am dung
tac dung » sach dung, xay dung, tin dung
cong ban » cong bang, cong tan, cong dan
cong san » cong tac
hang cau » hang dau, hang ca, nhung cau

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 chieu tinh - thanh trung ((tam dung) OR (tac dung)) ((cong ban) OR (cong san)) hang cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu tinh - thanh trung ((tam dung) OR (tac dung)) ((cong ban) or (cong san)) hang cau~".
• Adding a wildcard symbol may retrieve word variants: ho chieu tinh - thanh trung ((tam dung) OR (tac dung)) ((cong ban) or (cong san)) hang cau*.
