Perhaps you should try some spelling variations:
doanh bat » doanh tai, doanh va
danh sai » dung sai, danh dau, hanh san
danh bat » anh bai, dinh ba
te sach » toc sach
sach ky » sac ky, sach y, sach ty
thu xac » thau xay
hiem he » hiem xe, hieu he, thien he
cao hoi » cau hoi, co hoi, cao hoc
cua tre » cua te, cuu tre, cua triet
he nam » ha nam, nghe nam

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