Perhaps you should try some spelling variations:
danh vai » danh sai, danh va, doanh van
te sach » toc sach
nang xa » lang xa, nang ma, mang xa
hieu ve » hieu va, hieu van
ve chat » va chat, van chat
vai cua » dai cua, hai cua, lai cua
cua tre » cua te, cuu tre, cua triet
xuc va » tuc va, luc va, xac va

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sach y ((nang xa) OR (nang x)) hoi. hieu ve chat ((xuc va) or (duc va)) danh vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y ((nang xa) OR (nang x)) hoi. hieu ve chat ((xuc va) OR (duc va)) danh vai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y ((nang xa) OR (nang x)) hoi. hieu ve chat ((xuc va) or (duc va)) danh vai cua tre*".
