Perhaps you should try some spelling variations:
muong dai » duong dai, mung dai, tuong dai
xa muong » ca muong, xa truong, xa dong
cam tuc » cam xuc, nam thuc, dam thuc
hieu ve » hieu va, hieu van
so dac » so dan
cam tu » cam thu, nam tu, dam tu
ma hoi » mai hoi, ma hoa, me hoi
dac ky » cac ky, dan ky, sac ky
cua te » cua tu

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

• Performing a fuzzy search may retrieve terms with similar spellings: so dac ky nang ((ma hoi) OR (xa hoi)). hieu ve ((cam tuc) or (cam tu)) xa muong dai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so dac ky nang ((ma hoi) OR (xa hoi)). hieu ve ((cam tuc) OR (cam tu)) xa muong dai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so dac ky nang ((ma hoi) OR (xa hoi)). hieu ve ((cam tuc) or (cam tu)) xa muong dai cua te*".
