Perhaps you should try some spelling variations:
cam thuc » am thuc, nam thuc, cam thu
cuu tre » cua tre, cau tren, cau treo
dinh vi » dinh ve, dinh viet, dinh tri
dinh da » dinh dat, dinh dao, tinh da
hieu ve » hieu va, hieu van
thuc va » thuc vat, thuc dan, thuc day
vu sac » vu sach, va sac, vu cac
vu san » va san, vu ban
ve cam » ve cham, ve cac, va cam
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 sac) OR (vu san)) ky nang x hoi. hieu ve cam thuc va ((dinh da) or (dinh vi)) cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sac) OR (vu san)) ky nang x hoi. hieu ve cam thuc va ((dinh da) OR (dinh vi)) cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sac) OR (vu san)) ky nang x hoi. hieu ve cam thuc va ((dinh da) or (dinh vi)) cuu tre".
• Adding a wildcard symbol may retrieve word variants: ((vu sac) OR (vu san)) ky nang x hoi. hieu ve cam thuc va ((dinh da) or (dinh vi)) cuu tre*.
