I know the kind of instant noodles you are talking about. Generally, aunts and grandmothers set up stalls at the gates of rural primary and secondary schools to buy snacks for their children, and sometimes there are some there. I know it is sold at the entrance of Gezhuang Primary and Secondary School in Miyun Xitian. If I remember correctly, Daxing seems to have it. There is a Ren Woxing supermarket next to the station of Yuan Di Shopping Center. At first glance, it is selling mobile phones. In fact, it is a supermarket inside. I've seen it. I wonder if there is one now. I study there. Take the express 957 and get off at Yuan Di Shopping Center across the street.
