Perhaps you should try some spelling variations:
thu sach » tu sach, thuat sach, thuoc sach
cham xuc » chat xuc, cham soc, pham duc
va danh » va dinh, va dan, va hanh
hieu ve » hieu va, hieu van
nang xa » nang x, lang xa, nang ma
y nang » ky nang, ly nang, v nang
di cuu » di cua, dinh cuu
di cau » da cau, diem cau

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

• Performing a fuzzy search may retrieve terms with similar spellings: thu sach y nang xa hoi. hieu ve ((cham xuc) or (cam xuc)) va danh ((di cuu) OR (di cau)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach y nang xa hoi. hieu ve ((cham xuc) OR (cam xuc)) va danh ((di cuu) OR (di cau)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach y nang xa hoi. hieu ve ((cham xuc) or (cam xuc)) va danh ((di cuu) OR (di cau)) tre".
• Adding a wildcard symbol may retrieve word variants: thu sach y nang xa hoi. hieu ve ((cham xuc) or (cam xuc)) va danh ((di cuu) OR (di cau)) tre*.
