There were loads of food stalls lining the passages around the centre courtyard, and even more people trying to buy it... I didn't try hauling out a sketchbook and pen in the crush, but managed to get hold of a spring roll and settled to sketch one of the picnic groups with greasy fingers.
The Wishing Tree, where you have your name inscribed in Chinese calligraphy on a ribbon with a medallion attached, and throw it up into the tree while you make a wish. If the ribbon sticks there, your wish will come true during this Year of the Red Rooster. I didn't risk it! Nan Hua is a huge place and apparently we missed lots more interesting sights and events, but that was about all I could manage in the heat and crowds before the long drive home.
