Perhaps you should try some spelling variations:
phai nhuong » phan thuong, pham thuong, pham chuong
chieu xanh » chieu sach, chieu sang, chieu tinh
thanh tung » thanh cong
ho chieu » theo chieu, hoc thieu, doi chieu
ha nhung » hoa nhung, hay nhung, pha nhung
cong dan » cong tan, huong dan, cong dong
cong san » cong tac
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 - thanh tung ((ha nhung) OR (phai nhuong)) ((cong dan) OR (cong san)) toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - thanh tung ((ha nhung) or (phai nhuong)) ((cong dan) OR (cong san)) toan tap~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - thanh tung ((ha nhung) or (phai nhuong)) ((cong dan) OR (cong san)) toan tap*.
