Perhaps you should try some spelling variations:
thanh tuong » thanh thuong, thanh tung, thanh huong
doi chieu » doc hieu, doi chi, mot chieu
ho chieu » theo chieu, hoc thieu, mot chieu
tuong ca » truong ca, tuong cay, tuong cua
ca trong » cay trong, cad trong, co trong
cong tac » cong ty
phan cau » phan dau, phan cac, phan tu

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) OR (doi chieu)) xanh - thanh tuong ca trong ((cong san) OR (cong tac)) phan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (doi chieu)) xanh - thanh tuong ca trong ((cong san) OR (cong tac)) phan cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (doi chieu)) xanh - thanh tuong ca trong ((cong san) OR (cong tac)) phan cau*.
