Perhaps you should try some spelling variations:
thieu xanh » hieu manh, thien anh, thien danh
chieu xanh » chieu sach, chieu sang, chieu tinh
thanh tung » thanh cong
nhung cong » dung cong, thong cong, hang cong
ha nhung » hoa nhung, hay nhung, pha nhung
cong san » cong tac
tung ha » trung ha, dung ha, tung ho
hang ca » nang cao, hang tai, 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: hoc ((thieu xanh) OR (chieu xanh)) - thanh tung ha nhung cong san ((hang ca) OR (hang va))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu xanh) or (chieu xanh)) - thanh tung ha nhung cong san ((hang ca) OR (hang va))~".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu xanh) or (chieu xanh)) - thanh tung ha nhung cong san ((hang ca) OR (hang va))*.
