Perhaps you should try some spelling variations:
van nhanh » van thanh, van hanh, van khanh
nham thuc » nhan thuc, nam thuc, nham thu
thuc van » thuc vat, thuc dan, thuc va
nhanh li » nhanh vi, thanh loi, nhanh thi
hieu ve » hieu van
ca viet » va viet, co viet, san viet
hieu va » lieu va, hieu qua
su sac » su sach, su cac, su xac
sac ky » cac ky, sai ky
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: su sac ky nang x hoi. ((hieu ve) or (hieu va)) nham thuc van nhanh li ((ca viet) OR (hoa viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky nang x hoi. ((hieu ve) OR (hieu va)) nham thuc van nhanh li ((ca viet) OR (hoa viet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky nang x hoi. ((hieu ve) or (hieu va)) nham thuc van nhanh li ((ca viet) OR (hoa viet))*".
