Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
va thanh » gia thanh, ban thanh, va tinh
tu sach » thu sach, su sach, te sach
ly nang » ky nang, ly hang, ly vang
hieu va » lieu va, hieu qua
y nang » ky nang, v nang, may nang
va cam » va cham, va cac, va cao
xuc va » duc va, tuc va, luc va
cua tu » cua tuc, cua su, cua cu

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 sach ((y nang) OR (ly nang)) x ho. hieu va cam xuc va thanh san ((cua triet) OR (cua tu))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((y nang) OR (ly nang)) x ho. hieu va cam xuc va thanh san ((cua triet) or (cua tu))~".
• Adding a wildcard symbol may retrieve word variants: tu sach ((y nang) OR (ly nang)) x ho. hieu va cam xuc va thanh san ((cua triet) or (cua tu))*.
