Perhaps you should try some spelling variations:
phuong danh » phuong anh, phuong dinh, phuong thanh
phuong hanh » phuong thanh, phuong anh, phuong hoang
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh trinh » canh tranh, hanh chinh
ho chieu » theo chieu, hoc thieu, doi chieu
cua loai » cua luat, cua dai, cua hoi
toan cao » toan ban, toan tap
cua thi » cua thoi, cua toi, cua chi

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 thi) OR (cua loai)) ((phuong danh) OR (phuong hanh)) toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - hanh trinh ((cua thi) or (cua loai)) ((phuong danh) OR (phuong hanh)) toan cao~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - hanh trinh ((cua thi) or (cua loai)) ((phuong danh) OR (phuong hanh)) toan cao*.
