Perhaps you should try some spelling variations:
te sach » toc sach
sach ty » sach y, sach tu, sach thu
ty nang » ky nang, ty xang, ty hang
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
cam duc » cam xuc, cao duc, pham duc
va danh » va dinh, va dan, va hanh
doi cua » dai cua, hoi cua, dong cua
ve cam » ve cham, ve cac, va cam
di cua » dai cua, de cua, do cua

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty nang xa hoi. hieu ve cam duc va danh ((di cua) OR (doi cua)) triet~".
• Adding a wildcard symbol may retrieve word variants: te sach ty nang xa hoi. hieu ve cam duc va danh ((di cua) OR (doi cua)) triet*.
