Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
nhung cong » thong cong, hang cong, nhung don
hoc thieu » toc thieu, hoc hien
tranh cua » doanh cua, manh cua
dung cong » dung trong
phan cau » phan dau, phan tu, phan lap
phan cac » nhan cach, phan dau, phan lap

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: hoc thieu xanh - canh tranh cua ((nhung cong) OR (dung cong)) van ((phan cau) OR (phan cac))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - canh tranh cua ((nhung cong) OR (dung cong)) van ((phan cau) or (phan cac))~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - canh tranh cua ((nhung cong) OR (dung cong)) van ((phan cau) or (phan cac))*.
