Perhaps you should try some spelling variations:
thuc ban » thuoc ban, thu ban, thuc van
moi quan » mai quan, hai quan, co quan
thuc dan » thuc hanh, hoc dan, thuc vat
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
hoi cua » hoi chuc
te lai » te tai, te bai
lai ky » sai ky, dai ky
ve nam » he nam, va nam, le nam

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

• Performing a fuzzy search may retrieve terms with similar spellings: te lai ky nang xa hoi. hieu ve nam ((thuc ban) OR (thuc dan)) thanh ((moi quan) or (hoi cua)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te lai ky nang xa hoi. hieu ve nam ((thuc ban) OR (thuc dan)) thanh ((moi quan) OR (hoi cua)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te lai ky nang xa hoi. hieu ve nam ((thuc ban) OR (thuc dan)) thanh ((moi quan) or (hoi cua)) triet".
• Adding a wildcard symbol may retrieve word variants: te lai ky nang xa hoi. hieu ve nam ((thuc ban) OR (thuc dan)) thanh ((moi quan) or (hoi cua)) triet*.
