Perhaps you should try some spelling variations:
cau tre » cau tren, cau treo, cau tra
danh di » danh du, xanh di, danh dien
va danh » va dinh, va dan, va hanh
thuc va » thuc vat, thuc dan, thuc day
ve cac » va cac, vien cac
di cau » da cau, diem cau
vu sac » vu sach, vu san, va sac
sac ky » cac ky, sai ky
ve cam » ve cham, va cam, ve cai
x hoi » o hoi, x ho, 5 hoi

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

• Performing a fuzzy search may retrieve terms with similar spellings: vu sac ky nang ((x hoi) or (xa hoi)). hieu ((ve cam) OR (ve cac)) thuc va danh di cau tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sac ky nang ((x hoi) OR (xa hoi)). hieu ((ve cam) OR (ve cac)) thuc va danh di cau tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sac ky nang ((x hoi) or (xa hoi)). hieu ((ve cam) OR (ve cac)) thuc va danh di cau tre".
• Adding a wildcard symbol may retrieve word variants: vu sac ky nang ((x hoi) or (xa hoi)). hieu ((ve cam) OR (ve cac)) thuc va danh di cau tre*.
