Perhaps you should try some spelling variations:
sach ty » sach y, sach tu, sach thu
doi cua » dai cua, hoi cua
va hanh » van hanh, va thanh, va danh
te sach » toc sach
nang xa » nang x, lang xa, nang ma
ty nang » ky nang, ty xang, ty hang
ve chat » va chat, van chat
ve cam » ve cham, ve cac, va cam
xuc va » duc va, tuc va, luc va
di cua » dai cua, de cua, do 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: te sach ty nang xa hoi. hieu ((ve cam) OR (ve chat)) xuc va hanh ((di cua) OR (doi cua)) triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty nang xa hoi. hieu ((ve cam) or (ve chat)) xuc va hanh ((di cua) OR (doi cua)) triet~".
• Adding a wildcard symbol may retrieve word variants: te sach ty nang xa hoi. hieu ((ve cam) or (ve chat)) xuc va hanh ((di cua) OR (doi cua)) triet*.
