Perhaps you should try some spelling variations:
tu sach » thu sach, su sach, te sach
ty hang » ly hang, ty xang, thi hang
hang ca » hang va, nang cao, hang tai
thuc va » thuc vat, thuc dan, thuc day
sach ty » sach y, sach tu, sach thu
vi cua » vai cua, di cua
cua te » cua tu
tuc va » truc va, tuc xa, duc va
ve cac » va cac, vien cac
ve cam » ve cham, va cam, ve cai
ca hoi » cau hoi, cua hoi, xa hoi

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 ty hang ca hoi. hieu ((ve cam) or (ve cac)) ((tuc va) OR (thuc va)) hanh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty hang ca hoi. hieu ((ve cam) OR (ve cac)) ((tuc va) OR (thuc va)) hanh vi cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty hang ca hoi. hieu ((ve cam) or (ve cac)) ((tuc va) OR (thuc va)) hanh vi cua te*".
