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