Perhaps you should try some spelling variations:
cham xuc » cam xuc, chat xuc, cham soc
sach ky » sach y, sach ty, sach kem
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
ve cham » va cham, ve chat, vu cham
han tai » hang tai, nhan tai, toan tai
van tai » von tai, van tuan
sac ky » cac ky, sai ky
xuc va » duc va, tuc va, luc va
thiet » thieu

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 ky) OR (sac ky)) nang xa hoi. hieu ve cham xuc va ((han tai) OR (van tai)) va thiet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ky) or (sac ky)) nang xa hoi. hieu ve cham xuc va ((han tai) OR (van tai)) va thiet~".
• Adding a wildcard symbol may retrieve word variants: su ((sach ky) or (sac ky)) nang xa hoi. hieu ve cham xuc va ((han tai) OR (van tai)) va thiet*.
