Perhaps you should try some spelling variations:
cham luc » cham soc, nhan luc, cham cuu
va thanh » gia thanh, ban thanh, va tinh
thanh va » thanh van, hanh va, thanh ha
hieu ve » hieu va, hieu van
ve cham » va cham, ve chat, vu cham
cua tre » cuu tre, cua triet, dua tren
te sac » te sach, te cac, te san
sac ky » cac ky, sai ky
luc va » duc va, tuc va, loc va
cua te » cua tu

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: te sac ky nang ((ma hoa) OR (xa hoi)). hieu ve cham luc va thanh va ((cua tre) OR (cua te))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang ((ma hoa) or (xa hoi)). hieu ve cham luc va thanh va ((cua tre) OR (cua te))~".
• Adding a wildcard symbol may retrieve word variants: te sac ky nang ((ma hoa) or (xa hoi)). hieu ve cham luc va thanh va ((cua tre) OR (cua te))*.
