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, nang ma, mang xa
lang xa » lang ha, dang xay, lang van
hieu ve » hieu va, hieu van
ve cham » va cham, ve chat, vu cham
xuc van » duc van, luc van, vuc van
van han » van hanh, van phan, van nhan
han mai » han tai, ban mai, han mac
sac ky » cac ky, sai ky
thiet* » thieu*

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) or (lang xa)) hoi. hieu ve cham xuc van han mai va thiet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ky) OR (sac ky)) ((nang xa) OR (lang xa)) hoi. hieu ve cham xuc van han mai va thiet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ky) OR (sac ky)) ((nang xa) or (lang xa)) hoi. hieu ve cham xuc van han mai va thiet*".
