Perhaps you should try some spelling variations:
truong cong » trong cong, truong dong, truong long
lao truong » lap truong, lam truong, cao truong
theo chieu » theo tieu, ho chieu, thi chieu
hinh sinh » tinh sinh, hinh dinh, hinh kinh
theo chu » cho chu, chao chu, theo yeu
sinh lao » tinh lao, sinh lam, sinh ly
cong dan » cong san, cong tan, huong dan
toan cao » toan tap
toan ban » van ban

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 chieu) OR (theo chu)) tinh - hinh sinh lao truong cong dan ((toan cao) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) OR (theo chu)) tinh - hinh sinh lao truong cong dan ((toan cao) or (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) OR (theo chu)) tinh - hinh sinh lao truong cong dan ((toan cao) or (toan ban))*.
