Perhaps you should try some spelling variations:
thuc day » thuc dan, thuc vat
dung de » dung he, dung dat
dang de » dang deo, dang do, vang de
cuu tre » cua tre, cau tren, cau treo
sai ky » sac ky
ve cac » vien cac
vu sai » vu hai, vu san, vu dai
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: vu sai ky nang x hoi. hieu ((ve cac) or (va cac)) thuc day ((dang de) OR (dung de)) cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sai ky nang x hoi. hieu ((ve cac) OR (va cac)) thuc day ((dang de) OR (dung de)) cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sai ky nang x hoi. hieu ((ve cac) or (va cac)) thuc day ((dang de) OR (dung de)) cuu tre".
• Adding a wildcard symbol may retrieve word variants: vu sai ky nang x hoi. hieu ((ve cac) or (va cac)) thuc day ((dang de) OR (dung de)) cuu tre*.
