Perhaps you should try some spelling variations:
theo chieu » theo tieu, theo chu, thi chieu
trong danh » trong doanh, truong danh, trong anh
hanh tang » hanh trang, anh tang, hanh mang
ho chieu » hoc thieu, doi chieu, mot chieu
tang qua » tang quan, tang cua, tang quy
qua dung » quang dung, su dung, qua song
toan ban » van 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) OR (theo chieu)) sang - hanh tang qua dung trong danh ((doanh tai) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (theo chieu)) sang - hanh tang qua dung trong danh ((doanh tai) or (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) OR (theo chieu)) sang - hanh tang qua dung trong danh ((doanh tai) or (toan ban))*.
