Perhaps you should try some spelling variations:
dang cong » dung cong
nang cong » nang song, bang cong, hang cong
thong le » thong ke, trong le, thong lam
trong ky » trong ca, trong va, trong _
y thanh » ty thanh, _ thanh, o thanh
le nang » le tang, le dang, ke nang
ky dang » ky nang, ky danh

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( (ehon OR hon) y thanh cong ) or ((( thong le nang cong ) or ( trong ky dang cong ))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( (ehon OR hon) y thanh cong ) OR ((( thong le nang cong ) OR ( trong ky dang cong ))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( (ehon OR hon) y thanh cong ) or ((( thong le nang cong ) or ( trong ky dang cong ))))*".
