Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, kieu tinh
thanh dung » thanh duong, thanh tung, thanh hung
chau tinh » cuu tinh, ha tinh, cua tinh
hang dong » hang nong, hang cong, lang dong
hanh dong » anh dong, ha dong
san than » sang than, san thanh, ban than
than cao » toan cao, thai cao, than cap

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

• Performing a fuzzy search may retrieve terms with similar spellings: doi ((chieu tinh) OR (chau tinh)) - thanh dung va ((hang dong) or (hanh dong)) san than cao~.
• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chieu tinh) OR (chau tinh)) - thanh dung va ((hang dong) OR (hanh dong)) san than cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu tinh) OR (chau tinh)) - thanh dung va ((hang dong) or (hanh dong)) san than cao".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu tinh) OR (chau tinh)) - thanh dung va ((hang dong) or (hanh dong)) san than cao*.
