Yulin meatballs are divided into beef meatballs and pork meatballs. Because of its round shape, Yulin people call it "meat egg". It is said that the earliest meatballs were created by Liang Yexun, Liang's great-grandfather in the late Qing Dynasty, and this technology has never spread abroad. Before the founding of New China, Liang Yexun's son Liang Daji sold beef brisket powder in Naihe Bridge, Xihu Chi Park, Yuzhou District, Yulin City, and made dozens of kilograms of meatballs as ingredients by hand every day. Meatballs are delicious, crisp, slag-free, tender and delicious, attracting many repeat customers. During the Republic of China, Li Zongren was stationed in Yulin, and once his men gave him meatballs. Li Zongren liked them very much after tasting them. After leaving Yulin, Li Zongren sent his men to Yulin to buy meatballs, which made Liang Daji's meatballs famous. Before the founding of New China, Yulin Daily published an article introducing the replacement of Qiaoji beef brisket powder.

After the founding of New China, the West Lake Pool was filled and the Naihe Bridge was demolished, and the beef brisket powder of Liang Daji became the memory of the old Yulin people.

In 2000, the fourth generation of Liang inherited his ancestral business. At first, he just sold beef brisket powder and some meatballs in the street like his ancestors. With the development of Yulin economy, Liang saw the potential market of meatballs, so he managed meatballs and beef brisket powder separately. He introduced modern technology, constantly studied and improved it, and finally succeeded in combining modern technology with traditional handwork to produce meatballs with traditional taste. In 2008, Liang Wei registered the trademark of "Laobao" for Yulin meatballs, becoming the only enterprise in Yulin that registered the trademark of meatballs. "Laobao" was originally a Yulin dialect, meaning "naughty, naughty". It is this trademark full of local flavor that makes "Laobao" meatballs a household name in Yulin, and its products have entered local supermarkets, attracting foreign merchants.
