Perhaps you should try some spelling variations:
thieu manh » hieu manh, tien manh, trieu minh
trung tuan » trung thanh, trung tam, tran tuan
hoc thieu » toc thieu, hoc hien
trung cua » truong cua, trung cap, dung cua
hang cong » dang cong, hang nong, bang cong
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
toan cao » toan ban, toan tap

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 - hanh ((trung cua) OR (trung tuan)) hang cong dan toan cao~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu manh - hanh ((trung cua) OR (trung tuan)) hang cong dan toan cao*.
