Perhaps you should try some spelling variations:
nghe nam » nghe lam, nghiep nam, nghe nano
doan sai » doan hai, doan mai, doanh tai
thu nam » tu nam, thu nhap, thu nhat
dan sai » danh sai, dan tai, dan giai
te sach » toc sach
nang ma » tang ma, sang ma, nang cao
cua tre » cua te, cuu tre, cua triet
y nang » ky nang, ly nang, v nang
he nam » ha nam
ma hoi » mai hoi, xa hoi, ma hoa

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 y nang ma hoi. hieu ((he nam) OR (nghe nam)) thu nam ((dan sai) or (doan sai)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang ma hoi. hieu ((he nam) OR (nghe nam)) thu nam ((dan sai) OR (doan sai)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang ma hoi. hieu ((he nam) OR (nghe nam)) thu nam ((dan sai) or (doan sai)) cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach y nang ma hoi. hieu ((he nam) OR (nghe nam)) thu nam ((dan sai) or (doan sai)) cua tre*.
