Perhaps you should try some spelling variations:
thieu manh » hieu manh, tien manh, trieu minh
hoc thieu » toc thieu, hoc hien
lang cong » dang cong, bang cong, hang cong
trung va » truong va, trang va, trung tam
trung ha » trung hoc, trung tam, trung cap
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than cao » toan cao, thai cao, than cap

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu manh - thanh ((trung va) OR (trung ha)) lang cong dan than cao~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu manh - thanh ((trung va) OR (trung ha)) lang cong dan than cao*.
