Perhaps you should try some spelling variations:
thieu tinh » trieu tinh, chieu tinh, thien tinh
trong phat » trong thuat, trong nha, trong hoat
cong luong » cong thuong, nang luong, cong dong
hoc thieu » toc thieu, hoc hien
trong thu » trong nha
nang cong » nang song, dang cong, bang cong
luong van » luong va, duong van, luong vat

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 tinh - manh ((trong phat) OR (trong thu)) nang cong luong van ban~.
• Adding a wildcard symbol may retrieve word variants: hoc thieu tinh - manh ((trong phat) or (trong thu)) nang cong luong van ban*.
