Sorting Kotin先降后升排序

我正在尝试对多个参数的列表进行排序。。例如，一个值递减，第二个值递增，第三个值递减

 var people = listOf<People>(People("palazo", "ooo", 1),
            People("asdf", "cccc", 2),
            People("Maria", "ooo", 3),
            People("Helena", "ccccc", 3),
            People("Carlos", "ccc", 4),
            People("Jhon", "ooo", 2)
    )

你想要实现什么？你能详细说明并提供更多的模型数据吗？

   people.sortedWith(compareBy(People::name, People::lastName)) 
   //but mixing ascending and descending

val sortedPeople = people.sortedWith(
    compareByDescending(People::name)
        .thenBy(People::lastName)
        .thenByDescending(People::age)
)
