Perhaps you should try some spelling variations:
mai khoi » mai khoa, tai khoa, cac khoi
xach tay » canh tay
cham xuc » cam xuc, chat xuc, cham soc
minh vi » minh voi, dinh vi, minh va
xuc van » duc van, luc van, vuc van
va cham » va chat, va tham
hieu va » lieu va, hieu qua
mai hoi » dai hoi, lai hoi, mai doi
su viet » so viet
vi su » va su, ve su, ki su

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: tu ((xach tay) OR (sach y)) nang ((mai hoi) OR (mai khoi)). hieu va cham xuc van minh vi su viet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((xach tay) or (sach y)) nang ((mai hoi) OR (mai khoi)). hieu va cham xuc van minh vi su viet~".
• Adding a wildcard symbol may retrieve word variants: tu ((xach tay) or (sach y)) nang ((mai hoi) OR (mai khoi)). hieu va cham xuc van minh vi su viet*.
