Perhaps you should try some spelling variations:
nang xa » nang x, lang xa, nang ma
thuc va » thuc vat, thuc dan, thuc day
va hanh » van hanh, va thanh, va danh
cua tuc » cua duc, cua tu, cua thuoc
vu sac » vu sach, vu san, va sac
sac ky » cac ky, sai ky
ve nam » he nam, va nam, te nam
le nam » ly nam, he nam, le na
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)) thuc va hanh vi ((cua te) or (cua tuc))~.
• 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)) thuc va hanh vi ((cua te) OR (cua tuc)).
• 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)) thuc va hanh vi ((cua te) or (cua tuc))".
• Adding a wildcard symbol may retrieve word variants: vu sac ky nang xa hoi. hieu ((ve nam) OR (le nam)) thuc va hanh vi ((cua te) or (cua tuc))*.
