Perhaps you should try some spelling variations:
theo chieu » theo tieu, ho chieu, theo chu
chieu xanh » chieu sach, chieu sang, chieu tinh
thanh toan » thanh hoa, thanh san
hanh hang » thanh hang, hanh han, hanh mang
hang hang » nang hang, cang thang, hung thang
tong cong » trong cong, cong cong, dung cong
cua tong » cua cong, cua dong, cua nong

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 - ((hanh hang) OR (hang hang)) cua tong cong ((thanh toan) OR (tinh toan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu xanh - ((hanh hang) OR (hang hang)) cua tong cong ((thanh toan) or (tinh toan)) cau~".
• Adding a wildcard symbol may retrieve word variants: theo chieu xanh - ((hanh hang) OR (hang hang)) cua tong cong ((thanh toan) or (tinh toan)) cau*.
