Perhaps you should try some spelling variations:
hang tai » hang va, dung tai
cham xuc » cam xuc, chat xuc, cham soc
han tai » nhan tai, van tai, toan tai
sach ky » sac ky, sach y, sach ty
ve cham » va cham, ve chat, vu cham
hieu ve » hieu va, hieu van
nang xa » nang x, lang xa, nang ma
sai ky » sac 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 (sai ky)) nang xa hoi. hieu ve cham xuc va ((han tai) OR (hang tai)) va thiet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ky) or (sai ky)) nang xa hoi. hieu ve cham xuc va ((han tai) OR (hang tai)) va thiet~".
• Adding a wildcard symbol may retrieve word variants: su ((sach ky) or (sai ky)) nang xa hoi. hieu ve cham xuc va ((han tai) OR (hang tai)) va thiet*.
