Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, hieu manh
chieu tinh » trieu tinh, lieu tinh, chau tinh
manh trung » thanh trung, manh hung, sinh trung
manh tung » manh hung, thanh tung
cong tan » cong tac, cong san, cong thanh
tan tinh » tan thinh, ban tinh, man tinh
toan tap » toan ban

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