Perhaps you should try some spelling variations:
truong phuong » truong chung, truong trung, dung phuong
thieu manh » hieu manh, trieu minh, chieu xanh
tien manh » tien anh, tien thanh, tieng anh
hanh hang » thanh hang, hang hang, hanh han
va truong » van truong, xa truong, va thuong
dan than » dan chan, ban than, van than
van tuan » van quan, van ban, anh tuan

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 (tien manh)) - hanh hang va truong phuong ((dan than) OR (van tuan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu manh) OR (tien manh)) - hanh hang va truong phuong ((dan than) or (van tuan)) cau~".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu manh) OR (tien manh)) - hanh hang va truong phuong ((dan than) or (van tuan)) cau*.
