Woodcarving craftsman Chen Jinjie took 45 days to build a set of ancient architectural models with 5,200 chopsticks. This handmade work of 1.3 meters in length and 45 centimeters in height is named “Qiushan Yunju." Every small window and door of the model can be opened like a normal door and window and it is very stable, but there no nails or screws are used. Chen has been making chopstick house models since last year. He loves the aesthetics of classic gardens in China, so all models were designed in such a style.
