Perhaps you should try some spelling variations:
cuoc manh » cuoc thanh, cuoc tranh, cuoc cach
toc sach » hoc sach, doc sach, thuoc sach
hanh vai » hanh vi, hanh va, hanh tai
sach ty » sach y, sach tu, sach thu
vai cuu » vai cua
cuu tre » cua tre, cau tren, cau treo
hieu ve » hieu va, hieu van
ty tang » tay tang, ty xang, ty hang
ma hoi » mai hoi, xa hoi, me hoi
ve cac » va cac, vien cac

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

• Performing a fuzzy search may retrieve terms with similar spellings: toc sach ty tang ((ma hoi) or (ma hoa)). hieu ve cac ((cuoc manh) OR (suc manh)) hanh vai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach ty tang ((ma hoi) OR (ma hoa)). hieu ve cac ((cuoc manh) OR (suc manh)) hanh vai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach ty tang ((ma hoi) or (ma hoa)). hieu ve cac ((cuoc manh) OR (suc manh)) hanh vai cuu tre".
• Adding a wildcard symbol may retrieve word variants: toc sach ty tang ((ma hoi) or (ma hoa)). hieu ve cac ((cuoc manh) OR (suc manh)) hanh vai cuu tre*.
