Perhaps you should try some spelling variations:
lanh hai » manh hai, thanh hai, lang chai
te sach » toc sach
hieu ve » hieu va, hieu van
ve chat » va chat, van chat
hai cua » thai cua, dai cua, hoi cua
cua tre » cua te, cuu tre, cua triet
v nang » va nang, vu nang, van nang
luc va » tuc va, loc 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 ((ky nang) or (v nang)) xa hoi. hieu ve chat ((luc va) OR (duc va)) lanh hai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((ky nang) OR (v nang)) xa hoi. hieu ve chat ((luc va) OR (duc va)) lanh hai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ky nang) or (v nang)) xa hoi. hieu ve chat ((luc va) OR (duc va)) lanh hai cua tre*".
