Lu people are originally from Shandong. In the 1920s, he was forced to take his family to Fengtian (now Shenyang). At first, he opened a Shandong Dongda Alkali Bun Shop next to Fengtian North Market. With the unique diligence and simplicity of Shandong people, the business of the store is booming, but the Shandong people are not satisfied with it. He found that fresh meat buns made of dough were more popular with people, but he couldn't make them himself. According to friends, it is said that. Lv Ren didn't think much, and went to learn from the teacher with a gift. But the recipe of steamed stuffed bun is ancestral, and the master refused to teach him. He suffered a lot in order to make the master accept himself as a disciple. Lu Ren stood in front of the master for two days and one night in the heavy snow, so that his legs were frozen stiff. Later, the master was moved by the truth and finally accepted him as an apprentice.

After learning the real skills, the Lu people ended their own big alkali steamed bread shop and opened a noodle and meat bag shop. Because of its delicious and unique taste and real people, the store's business is extremely hot in a short time. At that time, soldiers always came to the store to buy steamed buns. It took a long time to know that Zhang always sent an adjutant to buy it. The news that "the prince also ate Lu Ji steamed buns" spread among the people. After a long time, Lu Ji's soup dumplings became "the prince's buns", and the business of Lu people's shops became more popular, and in just a few years it developed into more than a dozen branches in Fengtian.
