Perhaps you should try some spelling variations:
su sach » so sach, vu sach
sach ky » sac ky, sach y, sach ty
va tinh » may tinh
ve cuoc » va cuoc, ve duoc, ve nuoc
nang xa » nang x, lang xa, nang ma
ve coc » ve cac, ve co
luc va » duc va, tuc va, loc va
vi cua » vai cua
di cua » dai cua, doi cua, de cua

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 ky nang xa hoi. hieu ((ve coc) OR (ve cuoc)) luc va tinh ((vi cua) OR (di cua)) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky nang xa hoi. hieu ((ve coc) or (ve cuoc)) luc va tinh ((vi cua) OR (di cua)) tre~".
• Adding a wildcard symbol may retrieve word variants: su sach ky nang xa hoi. hieu ((ve coc) or (ve cuoc)) luc va tinh ((vi cua) OR (di cua)) tre*.
