-* It's derived from `AbpMongoDbContext` class.
-* Adds a public `IMongoCollection<TEntity>` property for each mongo collection. ABP uses these properties to create default repositories by default.
-* Overriding `CreateModel` method allows to configure collections (like their collection name in the database).
+* 继承 `AbpMongoDbContext` 类
+* 为每一个mongo集合添加一个公共的 `IMongoCollection<TEntity>` 属性。ABP默认使用这些属性创建默认的仓储
+* 重写 `CreateModel` 方法，可以在方法中配置集合（如设置集合在数据库中的名字）
 
-### Registering DbContext To Dependency Injection
