Perhaps you should try some spelling variations:
den thanh » de thanh, dinh thanh, dong thanh
canh tinh » hanh tinh, manh tinh, canh tranh
hee nhung » hien nhung, teen nhung, ve nhung
doan den » doan dien, dan den, don den
he nhung » ve nhung, me nhung, hien nhung
cong dan » cong san, cong tan, cong dong
toan cau » toan cao, toan ban, toan tap

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: doan den thanh - canh tinh ((he nhung) OR (hee nhung)) ((cong dan) OR (huong dan)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doan den thanh - canh tinh ((he nhung) or (hee nhung)) ((cong dan) OR (huong dan)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: doan den thanh - canh tinh ((he nhung) or (hee nhung)) ((cong dan) OR (huong dan)) toan cau*.
