Perhaps you should try some spelling variations:
thuc dan » thuc hanh, hoc dan, thuc vat
dan hanh » dang hanh, dan khanh, dan thanh
nang xa » nang x, lang xa, nang ma
vu sac » vu sach, vu san, va sac
sac ky » cac ky, sai ky
ve nam » he nam, va nam, te nam
le nam » he nam, le na, te nam
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 sac ky nang xa hoi. hieu ((ve nam) or (((le nam) OR (ly nam)))) thuc dan hanh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sac ky nang xa hoi. hieu ((ve nam) OR (((le nam) OR (ly nam)))) thuc dan hanh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sac ky nang xa hoi. hieu ((ve nam) or (((le nam) OR (ly nam)))) thuc dan hanh vi cua te".
• Adding a wildcard symbol may retrieve word variants: vu sac ky nang xa hoi. hieu ((ve nam) or (((le nam) OR (ly nam)))) thuc dan hanh vi cua te*.
