Perhaps you should try some spelling variations:
dung tren » dung trong, dung trung
thuat san » thuat toan, thuat song, thuat lanh
qua chao » qua cham, qua cho, qua khao
nang xa » nang x, lang xa, nang ma
anh vai » anh va, anh bai, anh van
san ky » sang ky, van ky, dan ky
su van » vu van
tu van » tu va
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: thuat san ky nang xa hoi. hieu qua chao ((su van) OR (tu van)) anh vai ((dung tren) or (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat san ky nang xa hoi. hieu qua chao ((su van) OR (tu van)) anh vai ((dung tren) OR (cua te))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat san ky nang xa hoi. hieu qua chao ((su van) OR (tu van)) anh vai ((dung tren) or (cua te))*".
