Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh tranh » canh tranh, hanh trinh, hanh trang
nhung lang » nhung van, nhung cong
nhanh lang » nhanh quang, nhanh thang, nhan dang
tranh cua » doanh cua, manh cua
ho chieu » theo chieu, hoc thieu, mot chieu
toan ban » van ban

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - hanh tranh cua ((nhung lang) OR (nhanh lang)) tinh toan ban~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - hanh tranh cua ((nhung lang) OR (nhanh lang)) tinh toan ban*.
