Perhaps you should try some spelling variations:
nhanh lang » nhanh quang, nhanh thang, nhan dang
thieu sang » chieu sang, thieu khang, thieu quang
hung luong » hung vuong, dung luong, hang luong
luong danh » cuong danh, luong manh, luong anh
hoc thieu » toc thieu, hoc hien

danh toan » manh toan, anh toan, dan toan
lan hung » van hung, luan chung, lan phuong

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: hoc thieu sang - ((hanh tung) OR (nhanh lang)) lan hung luong danh toan cau~.
• Adding a wildcard symbol may retrieve word variants: hoc thieu sang - ((hanh tung) or (nhanh lang)) lan hung luong danh toan cau*.
