Perhaps you should try some spelling variations:
thanh trung » thanh tung
thieu xanh » hieu manh, thien anh, thien danh
chieu xanh » chieu sach, chieu sang, chieu tinh
tuan duong » tuyen duong, tuong duong, van duong
tuan dung » tran dung, tan dung, tuan dang
cong tac » cong ty
tac phan » tac pham, tai phan, tac phat
phan lap » phan dau

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: toc ((thieu xanh) OR (chieu xanh)) - thanh trung ((tuan dung) OR (tuan duong)) cong tac phan lap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((thieu xanh) or (chieu xanh)) - thanh trung ((tuan dung) OR (tuan duong)) cong tac phan lap~".
• Adding a wildcard symbol may retrieve word variants: toc ((thieu xanh) or (chieu xanh)) - thanh trung ((tuan dung) OR (tuan duong)) cong tac phan lap*.
