Perhaps you should try some spelling variations:
ngang thanh » nang thanh, nganh thanh, ngan thanh
theo chieu » theo tieu, ho chieu, theo chu
chieu xanh » chieu sach, chieu sang, chieu tinh
nhung cong » thong cong, hang cong, nhung don
tranh cua » doanh cua, manh cua
dung cong » dung trong
thanh mau » hanh mau, thanh san, thanh hai
ban cua » ban quan

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 chieu xanh - canh ((tranh cua) OR (ban cua)) ((nhung cong) OR (dung cong)) ngang thanh mau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu xanh - canh ((tranh cua) or (ban cua)) ((nhung cong) OR (dung cong)) ngang thanh mau~".
• Adding a wildcard symbol may retrieve word variants: theo chieu xanh - canh ((tranh cua) or (ban cua)) ((nhung cong) OR (dung cong)) ngang thanh mau*.
