Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
qua cham » qua hai, qua cac, qua cua
truc va » thuc va, thuc vat, trung va
va cham » va chat, va tham
lang xa » lang ha, dang xay, lang van
ky lang » ky nang, ky dang, ky tang
can ky » van ky, dan ky, ban ky
luc va » duc va, tuc va, loc va
vi cua » vai cua, di cua
tu can » tu ban, tu cac, thu canh

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 can ky lang xa hoi. hieu ((qua cham) OR (va cham)) ((luc va) OR (truc va)) hanh vi cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu can ky lang xa hoi. hieu ((qua cham) OR (va cham)) ((luc va) or (truc va)) hanh vi cua triet~".
• Adding a wildcard symbol may retrieve word variants: tu can ky lang xa hoi. hieu ((qua cham) OR (va cham)) ((luc va) or (truc va)) hanh vi cua triet*.
