Perhaps you should try some spelling variations:
thuat san » thuat toan, thuat song, thuat lanh
nang xa » nang x, lang xa, nang ma
van anh » van thanh, van minh
san ky » sang ky, van ky, dan ky
ve tai » te tai, de tai, le tai
ve cac » va cac, vien cac
cua te » cua tu
tuan » quan, tran, luan

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 ((ve tai) or (ve cac)) xuc ((van anh) OR (tuan anh)) dai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat san ky nang xa hoi. hieu ((ve tai) OR (ve cac)) xuc ((van anh) OR (tuan anh)) dai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat san ky nang xa hoi. hieu ((ve tai) or (ve cac)) xuc ((van anh) OR (tuan anh)) dai cua te*".
