Perhaps you should try some spelling variations:
thanh tung » thanh cong
nhung cong » dung cong, thong cong, hang cong
chau tinh » cuu tinh, ha tinh, cac tinh
cua tinh » cua sinh, va tinh, ha tinh
cong dan » cong san, cong tan, huong dan
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.

• Performing a fuzzy search may retrieve terms with similar spellings: o ((chau tinh) OR (cua tinh)) - ((thanh tung) or (canh tranh)) va nhung cong dan chan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: o ((chau tinh) OR (cua tinh)) - ((thanh tung) OR (canh tranh)) va nhung cong dan chan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "o ((chau tinh) OR (cua tinh)) - ((thanh tung) or (canh tranh)) va nhung cong dan chan cau".
• Adding a wildcard symbol may retrieve word variants: o ((chau tinh) OR (cua tinh)) - ((thanh tung) or (canh tranh)) va nhung cong dan chan cau*.
