Perhaps you should try some spelling variations:
cua viet » ca viet, hoa viet, cua vat
ky sang » ky dang, ky tang, duy sang
mai hoi » mai khoi, dai hoi, lai hoi
tinh di » tinh doi, trinh di, tinh da
va tinh » may tinh
thuc va » thuc vat, thuc dan, thuc day
di cua » dai cua, doi cua, de cua
su sac » su sach, su cac, su xac
le na » le nam, le va, le ta

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

• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ((ky sang) OR (ky nang)) mai hoi. hieu ((le na) OR (ly nam)) thuc va tinh di cua viet~.
• Adding a wildcard symbol may retrieve word variants: su sac ((ky sang) or (ky nang)) mai hoi. hieu ((le na) or (ly nam)) thuc va tinh di cua viet*.
