Perhaps you should try some spelling variations:
thuc dan » thuc hanh, hoc dan, thuc vat
hanh vai » hanh va, hanh tai, hanh van
nang xa » nang x, lang xa, nang ma
qua cac » cua cac
su sac » su sach, su cac, su xac
sac ky » cac ky, sai ky
luc va » duc va, tuc va, loc 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: su sac ky nang xa hoi. hieu qua cac ((luc va) or (thuc dan)) ((hanh vai) OR (hanh vi)) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky nang xa hoi. hieu qua cac ((luc va) OR (thuc dan)) ((hanh vai) OR (hanh vi)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky nang xa hoi. hieu qua cac ((luc va) or (thuc dan)) ((hanh vai) OR (hanh vi)) cua te".
• Adding a wildcard symbol may retrieve word variants: su sac ky nang xa hoi. hieu qua cac ((luc va) or (thuc dan)) ((hanh vai) OR (hanh vi)) cua te*.
