Perhaps you should try some spelling variations:
trong trinh » trong tinh, trang trinh, trong thinh
chieu xanh » chieu sach, chieu sang, chieu tinh
truong cua » truong ca, truong quan, truong cao
truong va » truong dai, truong cao, truong dao
ho chieu » theo chieu, hoc thieu, doi chieu
ran cau » van cau, can cau, tran chau
ban cau » bang cau, ban can, van cau

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 ((truong cua) OR (truong va)) dung trong trinh ((ran cau) OR (ban cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - thanh ((truong cua) or (truong va)) dung trong trinh ((ran cau) OR (ban cau))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - thanh ((truong cua) or (truong va)) dung trong trinh ((ran cau) OR (ban cau))*.
