Perhaps you should try some spelling variations:
thanh trung » thanh tung
nhung cong » dung cong, thong cong, hang cong
tieu xanh » tieu danh, chieu xanh, dieu hanh
trung cua » truong cua, trung tuan, trung cap
cua nhung » va nhung
van thanh » van tuan
ban thanh » ban hanh, ban hang
dan than » dan chan, ban than, van than

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: theo tieu xanh - thanh trung cua nhung cong ((((van thanh) OR (ban thanh))) OR (dan than)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo tieu xanh - thanh trung cua nhung cong ((((van thanh) OR (ban thanh))) or (dan than)) cau~".
• Adding a wildcard symbol may retrieve word variants: theo tieu xanh - thanh trung cua nhung cong ((((van thanh) OR (ban thanh))) or (dan than)) cau*.
