Perhaps you should try some spelling variations:
thanh trung » thanh tung
thieu manh » tien manh, trieu minh, chieu xanh
hieu manh » chieu xanh, hieu nganh, dieu hanh
trung cua » truong cua, trung tuan, trung cap
dung cong » dung trong
doan phan » doanh phan, toan phan, doanh nhan
cua dung » cua dang, cua dong, qua dung
dan phan » dan chan, van phan, dam phan

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) OR (hieu manh)) - thanh trung cua dung cong ((dan phan) OR (doan phan)) lap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu manh) or (hieu manh)) - thanh trung cua dung cong ((dan phan) OR (doan phan)) lap~".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu manh) or (hieu manh)) - thanh trung cua dung cong ((dan phan) OR (doan phan)) lap*.
