The zongzi mentioned in tomb raiding novels usually referred to a traditional Chinese food, also known as "zongzi wrapped in leaves". It's a traditional zongzi made of zongzi leaves and glutinous rice. It's usually eaten during the Dragon Boat Festival. The history of dumplings can be traced back to ancient times. It was said that they were originally invented to commemorate Qu Yuan. Zongzi was usually filled with glutinous rice and then wrapped with various fillings such as meat, eggs, beans, etc. Different regions have different methods and tastes of zongzi. For example, the southern zongzi is mainly sweet, while the northern zongzi is a combination of salty and sweet. Zongzi has a profound meaning in Chinese culture. The leaves of the Zongzi symbolize Qu Yuan's patriotic spirit, while the glutinous rice symbolizes reunion and happiness. The fillings symbolize different emotions and meanings. Therefore, the image of rice dumplings that often appeared in literary works such as tomb robbing novels also reflected the importance and yearning people attached to traditional culture and history.
