Perhaps you should try some spelling variations:
vu sach » vu bach, vu khach
su sach » so sach
ty nang » ky nang, ty xang, ty hang
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
cac xuc » cam xuc, cac nuoc, chat xuc
dan vi » doan vi, don vi, dan va
ve cac » va cac, vien cac
va dan » ca dan, va dao, va dau
xuc va » duc va, tuc va, luc va
cua tu » cua tuc, cua su, cua cu

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((vu sach) OR (su sach)) ty nang xa hoi. hieu ve cac xuc va dan vi ((cua te) or (cua tu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sach) OR (su sach)) ty nang xa hoi. hieu ve cac xuc va dan vi ((cua te) OR (cua tu))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sach) OR (su sach)) ty nang xa hoi. hieu ve cac xuc va dan vi ((cua te) or (cua tu))*".
