Perhaps you should try some spelling variations:
van hanh » van thanh, ban hanh, van anh
chau phu » chau phi, chau au, chau tho
cau phuc » cau truc, huu phuc, van phuc
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
sach ky » sac ky, sach ty, sach kem
hanh di » hanh vi, hanh de, hang di
cua tre » cua te, cuu tre, cua triet
di cua » dai cua, doi cua, de cua

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: nuoc ((sach ky) OR (sach y)) nang xa hoi. hieu ve ((cau phuc) OR (chau phu)) van hanh di cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "nuoc ((sach ky) OR (sach y)) nang xa hoi. hieu ve ((cau phuc) or (chau phu)) van hanh di cua tre~".
• Adding a wildcard symbol may retrieve word variants: nuoc ((sach ky) OR (sach y)) nang xa hoi. hieu ve ((cau phuc) or (chau phu)) van hanh di cua tre*.
