This is Changchun - the Detroit of the East. On a street near Guangfu Road, vendors sell foreign currency and breathe the lively atmosphere. In a small shop, customers are crowded, and the buying and selling gods of Guangfu Road are the main consumers. Fast and warm food like a plate of dumplings is a must-have for fast food. Grandpa Sun's small shop has only sold three types of dumplings for over a decade: pork and pickled cabbage filling, pork and celery filling, and pork and chives filling. The beef platter of Grandpa Sun's is the perfect match for dumplings: beef marrow, beef tendon, and beef kidney are grilled together, with an unchanging taste for over a decade.

这里是长春——东方底特律。光复路附近的民俗用品一条街，叫卖着彼岸的货币，呼吸着热闹的人气。当商贩们忙着扩张势力，这里却有一丝静谧。无名小店里，顾客很拥挤，光复路的买卖大神是这里的消费主力。工商社会，时间宝贵，吃啥又快又暖胃——一盘饺子，是快餐必备，风卷残云地吃喝才能缓解劳累。孙大爷的无名小店，从来没有环境，偶尔没有服务，需要食客自助。但饺子的蒸汽，烤串的烟气，却汇成了谜一样的人气。酸菜肉馅、芹菜肉馅、韭菜肉馅，十几年来小店只卖这三样，不会出现选择困难，因为食客没得选。跟饺子搭配的是孙大爷的牛肉大套：牛骨髓、牛筋、牛大腰。不同部位，同在一炉烤，分量实在、卖相可爱，一把最普通的粗盐烤出的是十几年不变的味道。
