Perhaps you should try some spelling variations:
thanh dam » thanh dat, thanh nam, thanh tam
khoa tang » kho tang, khoa dang, khoa tieng
cham xuc » cam xuc, chat xuc, cham soc
tang van » dang van, hoang van, trong van
tu bach » vu bach, tu cach, tu hach
hieu va » lieu va, hieu qua
va cham » va chat, va tham
van hoi » van hoa, van hoc, van hoe
cua tre » cua te, cuu tre, cua triet
xuc va » duc va, tuc va, luc va
tu bac » tu ban, tu cac, tu bat

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 bach) OR (tu bac)) khoa tang van hoi. hieu va cham xuc va ((thanh dam) OR (lanh dao)) cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu bach) OR (tu bac)) khoa tang van hoi. hieu va cham xuc va ((thanh dam) or (lanh dao)) cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((tu bach) OR (tu bac)) khoa tang van hoi. hieu va cham xuc va ((thanh dam) or (lanh dao)) cua tre*.
