Perhaps you should try some spelling variations:
chat luc » chat xuc, chat lua, nhan luc
va hanh » van hanh, va thanh, va danh
va dinh » van dinh, va kinh, va tinh
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
va chat » van chat, va phat, cao chat
cua tre » cuu tre, cua triet, dua tren
te sac » te sach, te cac, te san
sac ky » cac ky, sai ky
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 xa hoi. hieu va chat luc ((va hanh) OR (va dinh)) vi ((cua tre) OR (cua te))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang xa hoi. hieu va chat luc ((va hanh) or (va dinh)) vi ((cua tre) OR (cua te))~".
• Adding a wildcard symbol may retrieve word variants: te sac ky nang xa hoi. hieu va chat luc ((va hanh) or (va dinh)) vi ((cua tre) OR (cua te))*.
