Perhaps you should try some spelling variations:
doanh van » doan van, doanh va, doanh ban
va triet » va thiet, va trien, ve triet
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
cua tre » cua te, cuu tre, cua triet
tuc vay » tuc va, tuc xay, thuc vat
te sac » te sach, te cac, te san
tu vay » tu va, tu van, tu cay
sac ky » cac ky, sai ky
ve cac » va cac, vien cac

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 ve cac ((tuc vay) OR (tu vay)) doanh van ((cua tre) or (va triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky nang xa hoi. hieu ve cac ((tuc vay) OR (tu vay)) doanh van ((cua tre) OR (va triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang xa hoi. hieu ve cac ((tuc vay) OR (tu vay)) doanh van ((cua tre) or (va triet))*".
