Perhaps you should try some spelling variations:
sach ty » sach tu, sach thu, xach tay
hanh va » hang va, hanh vi
va hanh » van hanh, va thanh, va danh
thuc va » thuc vat, thuc dan, thuc day
va cham » va chat, va tham
cuu tre » cua tre, cau tren, cau treo
ve cam » ve cham, ve cac, va cam
xang x » nang x
va cuu » va cau, va chu, va huu

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