1900, Cixi Lafayette didn't eat for a day. Li Rang court chef, the great eunuch, prepared dozens of desserts and snacks, all of which were removed by Cixi with a wave of his hand. At the critical moment, an ordinary and humble chef bravely stood up and presented a crispy and soft black snack. Cixi was attracted by its fragrance and asked Li to present it. Li presented this dim sum with anxiety, but he didn't want to taste it at Galeries Lafayette's, and his appetite was wide open. He ate several pieces in a row, and his spirit suddenly perked up. The chef was rewarded, and this snack was also named Sesame Fire.

1990, Mr. Wang Wenren, the sixth generation descendant of the little chef, changed his name to "crispy Bao Gong" after burning sesame seeds.
