Perhaps you should try some spelling variations:
banh hai » lanh hai, manh hai, bang hai
cham duc » pham duc, cham soc, pham duy
tu sach » thu sach, su sach, te sach
cua tre » cua te, cua triet, dua tren
va banh » va ban, va danh, va hanh
va cham » va chat, va tham
hieu va » lieu va, hieu qua
sach tu » sach thu, cach tu, sach ty
tang ma » mang may, tang van
lang xa » lang ha, dang xay, lang van
cuu tre » cau tren, cau treo

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 tu ((lang xa) or (tang ma)) hoi. hieu va cham duc va banh hai ((cua tre) OR (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach tu ((lang xa) OR (tang ma)) hoi. hieu va cham duc va banh hai ((cua tre) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach tu ((lang xa) or (tang ma)) hoi. hieu va cham duc va banh hai ((cua tre) OR (cuu tre))*".
