Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
huong cua » dung cua
tong cong » trong cong, cong cong, dung cong
danh toan » anh toan, dan toan, dang toan
manh toan » thanh toan, anh tuan, tinh toan
ho chieu » theo chieu, hoc thieu, doi chieu
hung cua » chung cua, khung cua, dung cua

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: ho chieu xanh - thanh ((hung cua) OR (huong cua)) tong cong ((danh toan) OR (manh toan)) cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - thanh ((hung cua) or (huong cua)) tong cong ((danh toan) OR (manh toan)) cao~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - thanh ((hung cua) or (huong cua)) tong cong ((danh toan) OR (manh toan)) cao*.
