Perhaps you should try some spelling variations:
sang tao » hang tai
su sach » so sach, vu sach
truc va » thuc va, thuc vat, trung va
tao hai » tao dai, tao tai, tai hai
va danh » va dinh, va dan, va hanh
di cua » dai cua, doi cua, de cua
vi cua » vai cua
ve cac » va cac, vien cac
y sang » _ sang, duy sang
ve cam » ve cham, va cam, ve cai

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

• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y sang tao hai. hieu ((ve cam) OR (ve cac)) truc va danh ((vi cua) OR (di cua)) te~.
• Adding a wildcard symbol may retrieve word variants: su sach y sang tao hai. hieu ((ve cam) or (ve cac)) truc va danh ((vi cua) or (di cua)) te*.
