Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, chau tinh
thanh tung » thanh cong
nhung cong » dung cong, thong cong, hang cong
doi chieu » doc hieu, doi chi, ho chieu
tam nhung » tham nhung, cam nhung, nam nhung
dan than » ban than, van than, dan toan
dan chan » dan gian, dan ca, van chat

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: doi chieu tinh - ((thanh trung) OR (thanh tung)) tam nhung cong ((dan than) OR (dan chan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu tinh - ((thanh trung) OR (thanh tung)) tam nhung cong ((dan than) or (dan chan)) cau~".
• Adding a wildcard symbol may retrieve word variants: doi chieu tinh - ((thanh trung) OR (thanh tung)) tam nhung cong ((dan than) or (dan chan)) cau*.
