Perhaps you should try some spelling variations:
chat xuc » chat huu, cam xuc, chao xu
su sach » so sach, vu sach
ty nang » ky nang, ty xang, ty hang
dinh de » dinh ve, dinh du, dinh le
va dinh » van dinh, va kinh, va tinh
hieu ve » hieu va, hieu van
sach ty » sach y, sach tu, sach thu
cac xuc » cam xuc, cac nuoc, cac cuoc
de cua » le cua, te cua, dieu cua
ma hoi » mai hoi, ma hoa, me hoi
cua te » cua tu

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 ty nang ((ma hoi) OR (xa hoi)). hieu ve ((cac xuc) OR (chat xuc)) va dinh de cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty nang ((ma hoi) or (xa hoi)). hieu ve ((cac xuc) OR (chat xuc)) va dinh de cua te~".
• Adding a wildcard symbol may retrieve word variants: su sach ty nang ((ma hoi) or (xa hoi)). hieu ve ((cac xuc) OR (chat xuc)) va dinh de cua te*.
