Hu spicy soup originated in Henan, is a soup snack composed of pepper, beef, vermicelli, fungus, etc., and is mostly eaten in the morning. Its style can be compared to the Hong Kong-style bowl wings, and when making the soup, appropriate thickening is added to make the soup become paste, and the entrance is thick and dense. However, the spicy soup focuses on pepper spiciness, and the spicy aroma is more prominent.

Ma Laosi started in Xi'an with a bowl of authentic Henan Hu spicy soup, which is quite popular with neighbors. The soup is thick and bright, the smell is fragrant, the proportion of fungus, vermicelli, bean skin and other ingredients is moderate, the amount of meat is too large, and the taste is rich. When eating, you can see obvious black peppercorns, spicy numb tongue, and it lasts for a long time. The scallion rape cake is a major feature here, the dough is crispy, oily but not greasy, soaked in the soup and eaten, it has a unique flavor.

Ma Laosi's spicy soup is pre-prepared, and the vegetable cakes are sliced and processed in the workshop where the food is served. Diners can enter the restaurant after purchasing a meal at the door, and often have to share a table with other diners. After the stall opens at 6 a.m., the surging flow of people can quickly fill the small space in the house, and late diners have to wait in line or take away, so be careful about the time allocation when they go. Each bowl of spicy soup is 7 yuan, and the vegetable cake is 3 yuan.
