Perhaps you should try some spelling variations:
thanh trung » thanh tung
chieu xanh » chieu sach, chieu sang, chieu tinh
trung cua » truong cua, trung tuan, trung cap
cua nhung » va nhung
cong manh » cong danh, duong manh, cong thanh
ho chieu » theo chieu, hoc thieu, doi chieu
cong tan » cong san, cong thanh, cong ty
cong tac » cong ty
toan cao » toan ban, toan tap

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