Perhaps you should try some spelling variations:
ve triet » va trien, su triet
hieu van » hieu va, thien van, lieu va
phan lap » phan dau
hanh lam » thanh lap, hanh kem, hanh va
xuc van » duc van, luc van, vuc van
sach ty » sach y, sach tu, sach thu
su sach » so sach, vu sach
hieu ve » hieu va
nang xa » nang x, lang xa, nang ma
ty nang » ky nang, ty xang, ty hang

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

• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty nang xa hoi. ((hieu ve) OR (hieu van)) cam xuc van ((hanh lam) OR (phan lap)) ve triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty nang xa hoi. ((hieu ve) OR (hieu van)) cam xuc van ((hanh lam) or (phan lap)) ve triet~".
• Adding a wildcard symbol may retrieve word variants: su sach ty nang xa hoi. ((hieu ve) OR (hieu van)) cam xuc van ((hanh lam) or (phan lap)) ve triet*.
