Perhaps you should try some spelling variations:
cham luc » cham soc, cham cuu, chat lua
nhan luc » nang luc
hanh vai » hanh vi, hanh va, hanh tai
te sach » toc sach
va hanh » van hanh, va thanh, va danh
ty nang » ky nang, ty xang, ty hang
hieu ve » hieu va, hieu van
sach ty » sach y, sach tu, sach thu
cua tu » cua tuc, cua su, cua cu
x hoi » xa hoi, o hoi, x ho

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 sach ty nang x hoi. hieu ve ((cham luc) OR (nhan luc)) va hanh vai ((cua te) OR (cua tu))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty nang x hoi. hieu ve ((cham luc) or (nhan luc)) va hanh vai ((cua te) OR (cua tu))~".
• Adding a wildcard symbol may retrieve word variants: te sach ty nang x hoi. hieu ve ((cham luc) or (nhan luc)) va hanh vai ((cua te) OR (cua tu))*.
