Perhaps you should try some spelling variations:
hanh vai » hanh vi, hanh va, hanh tai
tu sach » thu sach, te sach, tu cach
va cham » va chat, va tham
vai cuu » vai cua
va hanh » van hanh, va thanh, va danh
thuc va » thuc vat, thuc dan, thuc day
cuu tre » cua tre, cau tren, cau treo
su sach » so sach, vu sach
xang x » nang x
ve cam » ve cham, ve cac, va cam
x hoi » xa hoi, o hoi, x ho

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) OR (su sach)) ty xang x hoi. hieu ((ve cam) or (va cham)) thuc va hanh vai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (su sach)) ty xang x hoi. hieu ((ve cam) OR (va cham)) thuc va hanh vai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (su sach)) ty xang x hoi. hieu ((ve cam) or (va cham)) thuc va hanh vai cuu tre".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (su sach)) ty xang x hoi. hieu ((ve cam) or (va cham)) thuc va hanh vai cuu tre*.
