Perhaps you should try some spelling variations:
vat thanh » dat thanh, gat thanh, tat thanh
cam thuc » am thuc, nam thuc, cam thu
te sach » toc sach
lang xa » lang ha, dang xay, lang van
hieu ve » hieu va, hieu van
hai cua » thai cua, dai cua, hoi cua
ve cam » ve cham, ve cac, va cam
vi cua » vai cua, di cua

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach _ lang xa hoi. hieu ve cam thuc vat thanh ((vi cua) OR (hai cua)) te~".
• Adding a wildcard symbol may retrieve word variants: te sach _ lang xa hoi. hieu ve cam thuc vat thanh ((vi cua) OR (hai cua)) te*.
