Perhaps you should try some spelling variations:
thieu tinh » trieu tinh, chieu tinh, thien tinh
hoc thieu » toc thieu, hoc hien
manh hung » anh huong
chua nang » chua xang, kha nang, cuu nang
cong san » cong tac
san toan » van toan, dan toan, manh toan
toan ban » van ban
chuc » thuc, chu, phuc

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu tinh - manh hung ((chua nang) OR (chuc nang)) cong san toan ban~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu tinh - manh hung ((chua nang) OR (chuc nang)) cong san toan ban*.
