需要注意的是，价格决定了复购的频次：再好的产品，如果价格过高，也无法实现高复购。去年我们打造的王繁星面馆，一年只开了80家店，我坚决不让它扩张到300、400家，就是因为现炒浇头面易被模仿，30多元的客单价，一旦在一个城市密集开店，必然陷入内卷，最终害人害己。对于高价品牌，必须“聚焦” “极致” “克制”——聚焦核心品类，产品品质做到极致，克制门店数量。
Each of our services exposes an OpenAPI Swagger endpoint in our internal development environments. This endpoint serves a JSON response that defines the full API specification for all operations the service supports.
