Cookies. Cookies should be very common in our daily life, and many people like them very much. The Forbidden City can use this to make it into various styles, just like the style of copper coins. Cookies produced in different years are different, which can attract the public well and let us know more about the ancient material culture of China. Can also make a variety of different tastes, the price should be moderate to be more suitable for the public.
Besides cookies, you can also make cakes. Pastry should be the standard food in ancient China, just like when we watch TV series, we always see all kinds of cakes on the table, but what we usually eat is not as delicious as in TV series. If the Forbidden City grasps this point and makes cakes with ancient characteristics, I believe many people will like it.
The sale of ice cream in the Forbidden City shows that people love China culture very much. Most foods are similar, but they have their own styles and characteristics. Therefore, the Forbidden City can seize these opportunities to integrate China's traditional culture into these delicacies, so that more people can feel the traditional charm of China culture while tasting the delicacies.
