Perhaps you should try some spelling variations:
nhung tuong » nhung huong, nhung phuong, hung vuong
thanh tung » thanh cong
hieu lang » chieu sang, hieu quang, nhieu tang
dap nhung » vap nhung, va nhung, dap ung
tung dap » tung dan, trung dai, tuong dan
dan than » ban than, van than, dan toan
dan chan » dan gian, dan ca, van chat

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: ho ((chinh sach) OR (hieu lang)) - thanh tung dap nhung tuong ((dan than) OR (dan chan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chinh sach) or (hieu lang)) - thanh tung dap nhung tuong ((dan than) OR (dan chan)) cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chinh sach) or (hieu lang)) - thanh tung dap nhung tuong ((dan than) OR (dan chan)) cau*.
