Perhaps you should try some spelling variations:
thanh tung » thanh cong
tuan trong » thuan trong, quan trong, tran trong
cong tuan » cong tan, cong luan, cong thanh
chi xanh » chi anh, chi hanh, chieu xanh
chi danh » chi dan, chi anh, chi dinh
tuan cao » toan cao, juan cao, quang cao
cao cac » cho cac, cao cap, ca cac

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 ((chi xanh) OR (chi danh)) - ((thanh trung) OR (thanh tung)) tuan trong cong tuan cao cac~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chi xanh) OR (chi danh)) - ((thanh trung) or (thanh tung)) tuan trong cong tuan cao cac~".
• Adding a wildcard symbol may retrieve word variants: doi ((chi xanh) OR (chi danh)) - ((thanh trung) or (thanh tung)) tuan trong cong tuan cao cac*.
