Perhaps you should try some spelling variations:
dong luong » cong luong, dong duong, dong huong
hanh dang » hanh dong, hanh dung, hanh mang
theo chu » theo chieu, cho chu, chao chu
ho chieu » theo chieu, hoc thieu, doi chieu
anh dang » anh dong, anh dung, anh bang
luong va » dung va
toan ban » van ban
va toan » van toan, bai toan, tap toan

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) OR (ho chieu)) sang - ((hanh dang) OR (anh dang)) van dong luong va toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chu) or (ho chieu)) sang - ((hanh dang) OR (anh dang)) van dong luong va toan ban~".
• Adding a wildcard symbol may retrieve word variants: ((theo chu) or (ho chieu)) sang - ((hanh dang) OR (anh dang)) van dong luong va toan ban*.
