Perhaps you should try some spelling variations:
thanh tung » thanh cong
nhung cong » dung cong, thong cong, hang cong
cua tinh » cua sinh, va tinh, ha tinh
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than cao » toan cao, thai cao, than cap
ho cua » hoc cua, hoi cua, hoa cua

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

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