Signs: Don't Do Any of This!

Here's what you cannot do on the path along the lake in Beihai Park:

No: motorcycles (biycles?), picking the flowers, loitering, taxis, dropping ashes, blowing horns, rollerblading, playing ball, carrying firearms, walking dogs, or starting fires. I can't tell what the middle bottom direction is. Beihai (North Lake) is a beautiful park near the center of the city, within walking distance of the Forbidden City to the south and Houhai to the north.
