Perhaps you should try some spelling variations:
te sach » toc sach
ve cham » va cham, ve chat, vu cham
hang di » hang doi, hang vi, hang dien
va hang » van hang, va nang, va lang
thuc va » thuc vat, thuc dan, thuc day
cuu tre » cua tre, cau tren, cau treo
so sach » so sanh, bo sach, co sach
ve cam » ve cac, va cam, ve cai
di cuu » di cau, di cua, dinh cuu
x hoi » xa hoi, o hoi, x ho

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