Perhaps you should try some spelling variations:
cau tren » cu tren, dau tren, ca tren
hanh vai » hanh vi, hanh va, hanh tai
vu cham » va cham, vu kham, tu cham
vai cau » va cau, van cau, vai cac
va hanh » van hanh, va thanh, va danh
thuc va » thuc vat, thuc dan, thuc day
sach ty » sach tu, sach thu, xach tay
ve cham » va cham, ve chat, ve chim
ang xa » lang xa, mang xa, dang xay

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

• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach ty) OR (sach y)) ang xa hoi. hieu ((ve cham) or (vu cham)) thuc va hanh vai cau tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ty) OR (sach y)) ang xa hoi. hieu ((ve cham) OR (vu cham)) thuc va hanh vai cau tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ty) OR (sach y)) ang xa hoi. hieu ((ve cham) or (vu cham)) thuc va hanh vai cau tren".
• Adding a wildcard symbol may retrieve word variants: te ((sach ty) OR (sach y)) ang xa hoi. hieu ((ve cham) or (vu cham)) thuc va hanh vai cau tren*.
