Perhaps you should try some spelling variations:
trinh quan » tinh quang, trinh luat
hanh dang » hanh dong, hanh dung, hanh mang
hang cong » dang cong, hang nong, bang cong
theo chu » theo chieu, cho chu, chao chu
chu xang » chua xang, chu bang, chuc nang
anh dang » anh dong, anh dung, anh bang
cua hang » cua dang, cua nhung, cua cong

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: theo chu xang - ((hanh dang) OR (anh dang)) cua hang cong ((trinh han) OR (trinh quan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu xang - ((hanh dang) or (anh dang)) cua hang cong ((trinh han) OR (trinh quan)) cau~".
• Adding a wildcard symbol may retrieve word variants: theo chu xang - ((hanh dang) or (anh dang)) cua hang cong ((trinh han) OR (trinh quan)) cau*.
