nhung chong » nhung cong, nhung phong, phong chong
hanh nang » ganh nang, hanh mang, hanh trang
van thanh » ban thanh, van tuan
thanh lap » thanh san, phan lap, thanh hai
hoc dieu » hoc thieu, hoc hien
anh nang » ganh nang, anh bang, anh dang

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 dieu hanh - ((hanh nang) OR (anh nang)) quan ((nhung chong) OR (nhung phuong)) van thanh lap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc dieu hanh - ((hanh nang) OR (anh nang)) quan ((nhung chong) or (nhung phuong)) van thanh lap~".
• Adding a wildcard symbol may retrieve word variants: hoc dieu hanh - ((hanh nang) OR (anh nang)) quan ((nhung chong) or (nhung phuong)) van thanh lap*.
