I have a friend who is in Beijing for a few months. Here is one of his observations on the local fishermen:
. I was out and about the other day on my new bike and noticed these older gentlemen in the canal one was digging the fish out with a shovel , I saw him with possibly a dozen small fish in a net bag and then another chap with compressor, WOW: I thought right away of the Vedder canal. The other end of the canal has quite a bit of water as you can see from the pictures and these people were using proper fishing rods. The fish are no more than 4 to 5 inches long, I think it is some sort of a Bass.
Fun all over the world.
