Perhaps you should try some spelling variations:
su sach » so sach, vu sach
van cua » vang cua, ban cua, dan cua
va cham » va chat, va tham
ve cham » ve chat, vu cham, ve chim
nang xa » nang x, lang xa, nang ma
cua tre » cua te, cuu tre, cua triet
y nang » ky nang, ly nang, v nang
luc va » duc va, tuc va
loc va » hoc va

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sach y nang xa hoi. hieu ((ve cham) OR (va cham)) ((luc va) or (loc va)) dinh van cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y nang xa hoi. hieu ((ve cham) OR (va cham)) ((luc va) OR (loc va)) dinh van cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y nang xa hoi. hieu ((ve cham) OR (va cham)) ((luc va) or (loc va)) dinh van cua tre*".
