Perhaps you should try some spelling variations:
qua cham » qua hai, qua cac, va cham
cham xuc » cam xuc, chat xuc, cham soc
ban hang » ngan hang
dinh cuu » dinh chi
sach ky » sach y, sach ty, sach kem
nang xa » nang x, lang xa, nang ma
va hanh » van hanh, va thanh, va danh
cuu tre » cua tre, cau tren, cau treo
sac ky » cac ky, sai ky

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

• Performing a fuzzy search may retrieve terms with similar spellings: su ((sach ky) OR (sac ky)) nang xa hoi. hieu qua cham xuc ((va hanh) or (ban hang)) dinh cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ky) OR (sac ky)) nang xa hoi. hieu qua cham xuc ((va hanh) OR (ban hang)) dinh cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ky) OR (sac ky)) nang xa hoi. hieu qua cham xuc ((va hanh) or (ban hang)) dinh cuu tre*".
