Perhaps you should try some spelling variations:
nam thuc » nam thuoc, nam thu, nam tu
thanh vi » hanh vi, thanh ve, nhanh vi
thanh va » thanh van, hanh va, thanh ha
nang xa » nang x, lang xa, nang ma
hieu he » hieu ve, hiem he, hieu le
vu sai » vu hai, vu san, vu dai
sai 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: vu sai ky nang xa hoi. hieu he ((nam thuc) or (am thuc)) va ((thanh vi) OR (thanh va)) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sai ky nang xa hoi. hieu he ((nam thuc) OR (am thuc)) va ((thanh vi) OR (thanh va)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sai ky nang xa hoi. hieu he ((nam thuc) or (am thuc)) va ((thanh vi) OR (thanh va)) cua te".
• Adding a wildcard symbol may retrieve word variants: vu sai ky nang xa hoi. hieu he ((nam thuc) or (am thuc)) va ((thanh vi) OR (thanh va)) cua te*.
