Perhaps you should try some spelling variations:
hanh hai » thanh hai, nhanh hai, hang hai
su sach » vu sach
vu cham » va cham, vu kham, tu cham
hai cua » thai cua, dai cua, hoi cua
va hanh » van hanh, va thanh, va danh
cua tre » cua te, cuu tre, cua triet
ve cham » va cham, ve chat, ve chim
so sach » so sanh, bo sach, co sach
xuc va » duc va, tuc va, luc va
dan xa » dan xac, dan xay, dan ca

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) or (so sach)) hoa dan xa hoi. hieu ((ve cham) OR (vu cham)) xuc va hanh hai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (so sach)) hoa dan xa hoi. hieu ((ve cham) OR (vu cham)) xuc va hanh hai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (so sach)) hoa dan xa hoi. hieu ((ve cham) OR (vu cham)) xuc va hanh hai cua tre*".
