Perhaps you should try some spelling variations:
thanh truong » thanh trung, thanh thuong, thanh tung
truong cao » truong dai
nhung cong » thong cong, hang cong, nhung don
tieu xanh » tieu danh, chieu xanh, dieu hanh
dung cong » dung trong
phan cac » nhan cach, phan lap, phan van
phan dau » phan tu, hang 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: theo tieu xanh - thanh truong cao ((nhung cong) OR (dung cong)) dan ((phan cac) OR (phan dau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo tieu xanh - thanh truong cao ((nhung cong) or (dung cong)) dan ((phan cac) OR (phan dau))~".
• Adding a wildcard symbol may retrieve word variants: theo tieu xanh - thanh truong cao ((nhung cong) or (dung cong)) dan ((phan cac) OR (phan dau))*.
