Perhaps you should try some spelling variations:
ban hanh » ban hang
cuoc ban » quoc ban, buoc ban, coc ban
ve kham » vu kham, ve cham, ve khai
va kham » va cham, va khao, va tham
te sach » toc sach
nang xa » nang x, lang xa, nang ma
vi cua » vai cua, di cua
te sac » te cac, te san
cua te » cua tu

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) or (te sach)) ky nang xa hoi. hieu ((ve kham) OR (va kham)) cuoc ban hanh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sac) OR (te sach)) ky nang xa hoi. hieu ((ve kham) OR (va kham)) cuoc ban hanh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sac) or (te sach)) ky nang xa hoi. hieu ((ve kham) OR (va kham)) cuoc ban hanh vi cua te".
• Adding a wildcard symbol may retrieve word variants: ((te sac) or (te sach)) ky nang xa hoi. hieu ((ve kham) OR (va kham)) cuoc ban hanh vi cua te*.
