I went to Zibo for a business trip and went to Zhoucun. It originated from the delicious biscuits brought back by my former colleagues on business trips. I went to the field and found that this sesame cake was built as a museum. You can see the master made on the spot. To be honest, it is really delicious. Although it is expensive, it is really different from the cheap bought outside the online Taobao and the museum. It is thin and crisp. It is worth it!
