Perhaps you should try some spelling variations:
vay doanh » van doanh, ly doanh, voi doanh
va doanh » van doanh, hoa doanh, voi doanh
cham tuc » nham thuc, pham thuc, tham thuc
van cua » vang cua, ban cua, dan cua
va danh » va dinh, va dan, va hanh
te sach » toc sach
sach ky » sac ky, sach y, sach ty
ve cham » va cham, ve chat, vu cham
hieu ve » hieu va, hieu van
nang xa » nang x, lang xa, nang ma
cua tre » cua te, cuu tre, cua triet

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky nang xa hoi. hieu ve cham tuc ((((va doanh) OR (vay doanh))) or (va danh)) van cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang xa hoi. hieu ve cham tuc ((((va doanh) OR (vay doanh))) OR (va danh)) van cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang xa hoi. hieu ve cham tuc ((((va doanh) OR (vay doanh))) or (va danh)) van cua tre*".
