Perhaps you should try some spelling variations:
ban danh » ban doanh, ban hanh, ban dan
sach ky » sach y, sach ty, sach kem
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
ban anh » ban hanh, ban banh, bang anh
hai cuu » hai cua, hai chu, hai cuc
cuu tre » cua tre, cau tren, cau treo
sac ky » cac ky, sai ky
ve cam » ve cham, ve cac, va cam

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 ky) or (sac ky)) nang xa hoi. hieu ve cam xuc ((ban anh) OR (ban danh)) hai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (sac ky)) nang xa hoi. hieu ve cam xuc ((ban anh) OR (ban danh)) hai cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) or (sac ky)) nang xa hoi. hieu ve cam xuc ((ban anh) OR (ban danh)) hai cuu tre*".
