What are the interesting cold knowledge in traditional cross talk?

When I like cross talk, I learned that the White House system is old, and the "lock of hair" I mentioned when I threw paper money was old local news. "On Playing Cards" mentioned some things in the three cities south of Tianjin, regardless of national boundaries. Not to mention the changes in the old times such as the Eighth National Congress of the Communist Party of China, registration and selling cloth heads. Mr. Hou's "Three Bangs and Drums" and "Chord Tunes" talked about the status of Go lovers in the old days. Duet: Hua, a famous writer.
