Perhaps you should try some spelling variations:
va thanh » gia thanh, ban thanh, va tinh
thanh vi » hanh vi, thanh va, thanh ve
su sach » so sach, vu sach
lang xa » lang ha, dang xay, lang van
van dam » van dao, van dau, van dan
cua tre » cua te, cuu tre, cua triet
y lang » o lang, _ lang, tay lang
xuc va » duc va, tuc va, luc va
vi cua » vai cua, di cua

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: su sach y lang xa hoi. hieu ((((van dam) OR (van nam))) or (van lam)) xuc va thanh vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y lang xa hoi. hieu ((((van dam) OR (van nam))) OR (van lam)) xuc va thanh vi cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y lang xa hoi. hieu ((((van dam) OR (van nam))) or (van lam)) xuc va thanh vi cua tre*".
