Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang, nhieu tang
manh trung » manh tung, thanh trung, manh hung
trung dap » trung cap, trung dai, trung dam
dap trong » dat trong, dao trong, dai trong
manh toan » thanh toan, anh tuan, tinh toan
ban than » ban thanh, van thanh, ban hang

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 sang)) - manh trung dap trong cong ((manh toan) OR (ban than)) cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu sang)) - manh trung dap trong cong ((manh toan) or (ban than)) cap~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) OR (chieu sang)) - manh trung dap trong cong ((manh toan) or (ban than)) cap*.
