Perhaps you should try some spelling variations:
nhieu tang » chieu sang, hieu lang, nhiet nang
trinh cua » tinh cua, trinh quan, trinh luan
nong cong » cong cong, tong cong, nang cong
ho nhieu » hop nhieu, ho chieu, he nhieu
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
toan ban » van ban

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: "ho nhieu tang - hanh ((trinh cua) OR (trinh luat)) nong cong dan toan ban~".
• Adding a wildcard symbol may retrieve word variants: ho nhieu tang - hanh ((trinh cua) OR (trinh luat)) nong cong dan toan ban*.
