Perhaps you should try some spelling variations:
danh lai » danh sai, gianh lai, dinh lam
te sach » toc sach
lai cua » dai cua, hai cua, lai chau
va danh » va dinh, va dan, va hanh
cua tre » cua te, cuu tre, cua triet
may hoi » may thoi, tay hoi, mai hoi
ke mang » ke nang, ke trang
ky mang » ky nang, ky dang, ky tang
va cam » va cham, va cac, va cao
ve cam » ve cham, ve cac, ve cai

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 mang) OR (ke mang)) may hoi. hieu ((ve cam) or (va cam)) duc va danh lai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((ky mang) OR (ke mang)) may hoi. hieu ((ve cam) OR (va cam)) duc va danh lai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ky mang) OR (ke mang)) may hoi. hieu ((ve cam) or (va cam)) duc va danh lai cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ((ky mang) OR (ke mang)) may hoi. hieu ((ve cam) or (va cam)) duc va danh lai cua tre*.
