Perhaps you should try some spelling variations:
nhieu tang » chieu sang, hieu lang, nhiet nang
dung cong » dung trong
ho nhieu » hop nhieu, ho chieu, he nhieu
tung bay » tuong ban, tung dan, vung bao
vung bay » vung bao, vung tay, vung bac
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than cau » toan cau, phan cau, than cap
tung ap » tang ap, tung dan, tung mai

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

• Performing a fuzzy search may retrieve terms with similar spellings: ho nhieu tang - thanh ((tung ap) or (((tung bay) OR (vung bay)))) dung cong dan than cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho nhieu tang - thanh ((tung ap) OR (((tung bay) OR (vung bay)))) dung cong dan than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho nhieu tang - thanh ((tung ap) or (((tung bay) OR (vung bay)))) dung cong dan than cau".
• Adding a wildcard symbol may retrieve word variants: ho nhieu tang - thanh ((tung ap) or (((tung bay) OR (vung bay)))) dung cong dan than cau*.
