Perhaps you should try some spelling variations:
doanh van » doan van, doanh va, doanh ban
va doanh » van doanh, vay doanh, va danh
tu sach » thu sach, su sach, te sach
vu cham » vu kham, tu cham, qua cham
van cua » vang cua, ban cua, dan cua
va cham » va chat, va tham
ve cham » ve chat, ve chim, viet cham
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

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

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