Perhaps you should try some spelling variations:
thieu manh » hieu manh, tien manh, trieu minh
nhung cong » dung cong, thong cong, hang cong
van phuong » va phuong, van chuong, van phung
hoc thieu » toc thieu, hoc hien
van phong » van dong, hai phong
tung dap » trung dai, tuong dan, tuong dao
tung dan » dung dan, huong dan, trung dai

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 - thanh ((tung dap) OR (tung dan)) nhung cong ((van phuong) OR (van phong)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu manh - thanh ((tung dap) OR (tung dan)) nhung cong ((van phuong) or (van phong)) cau~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu manh - thanh ((tung dap) OR (tung dan)) nhung cong ((van phuong) or (van phong)) cau*.
