Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
nhung cong » dung cong, thong cong, hang cong
thanh toan » thanh hoa, thanh san, tinh toan
trinh vat » trinh van, sinh vat, trinh han
manh toan » anh tuan, tinh toan
ho chieu » theo chieu, hoc thieu, doi chieu

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