Perhaps you should try some spelling variations:
nhung tuong » nhung huong, nhung phuong, hung vuong
thi phuong » thi truong
lieu tinh » trieu tinh, diep tinh, bien tinh
canh manh » lanh manh, canh tranh, cach mang
dung cong » dung trong
manh cua » doanh cua, ban cua
dan chan » dan gian, dan ca, van chat
chan cau » phan cau, can cau, chinh cau

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: du lieu tinh - canh manh cua ((((nhung tuong) OR (thi phuong))) OR (dung cong)) dan chan cau~.
• Adding a wildcard symbol may retrieve word variants: du lieu tinh - canh manh cua ((((nhung tuong) or (thi phuong))) or (dung cong)) dan chan cau*.
