Perhaps you should try some spelling variations:
nghiep nam » nghiep va, nghiep tai, nghiep nho
nghe nam » nghe lam, nghe nano, nghe nhan
danh dai » danh dau, danh di, danh sai
tu sach » thu sach, te sach, tu cach
su sach » so sach, vu sach
thuc xa » thuc xay, tuc xa, thuc va
xa danh » va danh, dia danh, nam danh
cua tre » cua te, cuu tre, cua triet
y nang » ky nang, ly nang, v nang
x hoi » xa hoi, o hoi, x ho

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) or (su sach)) y nang x hoi. hieu ((nghe nam) OR (nghiep nam)) thuc xa danh dai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (su sach)) y nang x hoi. hieu ((nghe nam) OR (nghiep nam)) thuc xa danh dai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (su sach)) y nang x hoi. hieu ((nghe nam) OR (nghiep nam)) thuc xa danh dai cua tre".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (su sach)) y nang x hoi. hieu ((nghe nam) OR (nghiep nam)) thuc xa danh dai cua tre*.
