Perhaps you should try some spelling variations:
thieu manh » hieu manh, tien manh, trieu minh
trung tuan » trung thanh, trung tam, tran tuan
truong cua » truong ca, truong quan, truong cao
cong khanh » cong thanh, cong khan, cong nhan
hoc thieu » toc thieu, hoc hien
cong hach » cong sach, cong thanh, trong hach
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: hoc thieu manh - manh ((trung tuan) OR (truong cua)) nhung ((cong hach) OR (cong khanh)) toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu manh - manh ((trung tuan) or (truong cua)) nhung ((cong hach) OR (cong khanh)) toan ban~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu manh - manh ((trung tuan) or (truong cua)) nhung ((cong hach) OR (cong khanh)) toan ban*.
