Perhaps you should try some spelling variations:
tu sach » thu sach, su sach, te sach
vai cua » dai cua, hai cua, lai cua
anh vai » anh va, anh bai, anh van
van anh » van thanh, tuan anh, van minh
xuc van » duc van, luc van, vuc van
cua tre » cua te, cuu tre, cua triet
van hoi » van hoa, van hoc, van hoe
ky dang » ky nang, ky danh
ky lang » ky nang, ky tang, tay lang
ve cac » va cac, vien cac
ve cau » ke cau, va cau, le cau

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 sach ((ky lang) OR (ky dang)) van hoi. hieu ((ve cau) OR (ve cac)) xuc van anh vai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((ky lang) OR (ky dang)) van hoi. hieu ((ve cau) or (ve cac)) xuc van anh vai cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu sach ((ky lang) OR (ky dang)) van hoi. hieu ((ve cau) or (ve cac)) xuc van anh vai cua tre*.
