Perhaps you should try some spelling variations:
ve cham » va cham, vu cham, ve chim
ve chat » va chat, van chat
han tai » hang tai, nhan tai, toan tai
van tai » von tai, van tuan
su sac » su sach, su cac, su xac
sac ky » cac ky, sai ky
xuc va » duc va, tuc va, luc va
x hoi » xa hoi, o hoi, x ho
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 sac ky nang x hoi. hieu ((ve cham) OR (ve chat)) xuc va ((han tai) OR (van tai)) va thiet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky nang x hoi. hieu ((ve cham) or (ve chat)) xuc va ((han tai) OR (van tai)) va thiet~".
• Adding a wildcard symbol may retrieve word variants: su sac ky nang x hoi. hieu ((ve cham) or (ve chat)) xuc va ((han tai) OR (van tai)) va thiet*.
