Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
tinh vi » trinh vi, tinh voi, tinh va
van lam » van nam
cua tre » cua te, cuu tre, cua triet
lang xa » lang ha, dang xay, lang van
ky lang » ky nang, ky dang, ky tang
thu san » thuy san, thu ban, phu san
xuc va » tuc va, luc va, xac va
vi cua » vai cua, di cua
tu san » tu ban, tu can, vu san

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 san) OR (thu san)) ky lang xa hoi. hieu van lam ((xuc va) OR (duc va)) tinh vi cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu san) or (thu san)) ky lang xa hoi. hieu van lam ((xuc va) OR (duc va)) tinh vi cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((tu san) or (thu san)) ky lang xa hoi. hieu van lam ((xuc va) OR (duc va)) tinh vi cua tre*.
