That is Gong Ting’s genuine new hand-painted Guangzhou comic postcard from my childhood, Old Guangzhou Impression Postcard, and I have been looking for it for a long time.

On TB, there are "Qilou", "Tingzai Porridge", "Old Xiguan's Wedding", "Heavy Rain, Flooded Street", Pavilion, Flower Step Bricks, Two Pieces in a Cup, and Fried Land Snails on the Long Beach.
