Which is the most authentic Luoyang beef soup?

I think Luoyang beef soup is the most authentic:

1, Majieshan Beef Soup Restaurant: Speaking of this soup shop, no one should question its position in the whole Luoyang Beef Soup Restaurant. Ma Jie San beef soup shop, located at No.235, Qi Ming East Road, Chanhehuizu District, Luoyang City, is one of the famous soup shops in Luoyang.

2, Nanguan small bowl of beef soup: to say where Luoyang eats the most authentic food, no one in the old city of Luoyang can match. I once heard my parents clap their chests and say, "Unreal Luoyang snacks won't last long in the old streets."

3. Xiaolangdiu Beef Soup Restaurant: Xiaolangdiu Beef Soup Restaurant is located opposite the Industrial and Commercial Bank of Chundu New Village, Chundu Road, Xigong District. This store, formerly known as "Xiao Lang Beef Soup", has been open for more than 20 years. As an old shop, there are naturally many loyal fans. The store specializes in beef soup. At noon, there are beef noodles and beef Huimian Noodles, which are quite rich.

4. Master He Niu Yan Tang: Master He Niu Yan Tang is located 50 meters east of the entrance of Fiona Fang Yuan Yuming, Xinpeng South Road, Yichuan County. The biggest feature of this shop is that beef soup is made of whole cow, and the taste is naturally not bad.
