Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
quan dung » quang dung, quan duong, qua dung
dung cong » dung trong
cong danh » cuong danh, cong dan, cong thanh
ho chieu » theo chieu, hoc thieu, doi chieu
hang ban » hang luan, hang va, hang dau
hang tai » hang va, dung tai
toan tai » toan tap, doanh tai, toan ban
toan cao » toan ban, toan tap

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 - ((hang ban) OR (hang tai)) quan dung cong danh ((toan tai) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - ((hang ban) OR (hang tai)) quan dung cong danh ((toan tai) or (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - ((hang ban) OR (hang tai)) quan dung cong danh ((toan tai) or (toan cao))*.
