Perhaps you should try some spelling variations:
thieu manh » hieu manh, tien manh, trieu minh
sinh trong » sinh truong, sinh trung, dinh trong
tuan thong » toan thong, tuan phong, xuan thong
tran thong » toan thong, tran hong, tran trong
hoc thieu » toc thieu, hoc hien
tam thanh » nam thanh, am thanh, dam thanh
tam than » ban than

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 - sinh trong ((tuan thong) OR (tran thong)) thong ((tam than) OR (tam thanh)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu manh - sinh trong ((tuan thong) OR (tran thong)) thong ((tam than) or (tam thanh)) cau~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu manh - sinh trong ((tuan thong) OR (tran thong)) thong ((tam than) or (tam thanh)) cau*.
