Perhaps you should try some spelling variations:
phuong hanh » phuong thanh, phuong anh, phuong danh
hanh tranh » canh tranh, hanh trinh, hanh trang
huong vanh » duong vanh, phuong danh, huong dan
hoc chieu » hoc thieu, ho chieu, hoc hien
doi chieu » doc hieu, doi chi, ho chieu
tranh cua » doanh cua, manh cua
cua nhung » va nhung
tuan ban » tuan bang, toan ban, luan 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: ((hoc chieu) OR (doi chieu)) xanh - hanh tranh cua nhung ((huong vanh) OR (phuong hanh)) tuan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc chieu) or (doi chieu)) xanh - hanh tranh cua nhung ((huong vanh) OR (phuong hanh)) tuan ban~".
• Adding a wildcard symbol may retrieve word variants: ((hoc chieu) or (doi chieu)) xanh - hanh tranh cua nhung ((huong vanh) OR (phuong hanh)) tuan ban*.
