Perhaps you should try some spelling variations:
thanh tung » thanh cong
lieu tinh » trieu tinh, diep tinh, bien tinh
nam nhung » cam nhung, tham nhung, va nhung
cong dan » cong tan, huong dan, cong dong
cong san » cong tac
chan cau » phan cau, can cau, chinh cau
ho lieu » so lieu, co lieu, ho kieu

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 lieu tinh - ((thanh trung) OR (thanh tung)) nam nhung ((cong dan) OR (cong san)) chan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho lieu tinh - ((thanh trung) or (thanh tung)) nam nhung ((cong dan) OR (cong san)) chan cau~".
• Adding a wildcard symbol may retrieve word variants: ho lieu tinh - ((thanh trung) or (thanh tung)) nam nhung ((cong dan) OR (cong san)) chan cau*.
