Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
trinh cua » tinh cua, trinh quan, trinh luan
chong van » thong van, hong van, chong va
phong van » phung van, thong van, phong va
thanh mau » hanh mau, thanh san, thanh hai
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 cua) OR (trinh luat)) nhung ((chong van) OR (phong van)) thanh mau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - hanh ((trinh cua) or (trinh luat)) nhung ((chong van) OR (phong van)) thanh mau~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - hanh ((trinh cua) or (trinh luat)) nhung ((chong van) OR (phong van)) thanh mau*.
