Perhaps you should try some spelling variations:
su triet » su viet, su tien, ve triet
cham vuc » cham soc, pham duc, cham cuu
nang xa » nang x, lang xa, nang ma
thu ban » thu hang
va cham » va chat, va tham
vuc van » duc van, luc van, thuc van
hanh di » hanh vi, hang di, danh di
hanh de » hanh ve, hanh kem
thu san » thuy san, phu san, thuat san

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((thu san) OR (thu ban)) ky nang xa hoi. lieu va cham vuc van ((hanh di) or (hanh de)) su triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu san) OR (thu ban)) ky nang xa hoi. lieu va cham vuc van ((hanh di) OR (hanh de)) su triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu san) OR (thu ban)) ky nang xa hoi. lieu va cham vuc van ((hanh di) or (hanh de)) su triet".
• Adding a wildcard symbol may retrieve word variants: ((thu san) OR (thu ban)) ky nang xa hoi. lieu va cham vuc van ((hanh di) or (hanh de)) su triet*.
