Perhaps you should try some spelling variations:
thuc day » thuc dan, thuc vat
su triet » su viet, su tien, ve triet
ve cham » va cham, ve chat, vu cham
thuc va » thuc vat, thuc dan
nang xa » nang x, lang xa, nang ma
danh di » danh du, xanh di, danh dien
va cam » va cham, va cac, va cao
sac ky » cac ky, sai ky
te sac » te sach, te cac, te san
di su » doi su, ki su, da su

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sac ky nang xa hoi. hieu ((va cam) or (ve cham)) ((thuc va) OR (thuc day)) danh di su triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky nang xa hoi. hieu ((va cam) OR (ve cham)) ((thuc va) OR (thuc day)) danh di su triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang xa hoi. hieu ((va cam) or (ve cham)) ((thuc va) OR (thuc day)) danh di su triet*".
