数据库API，db.collection.orderBy函数的fieldPath参数不可以是汉字吗？
因为数据库里的字段名已经使用汉字了，并且试验过where用汉字做条件没问题，但orderBy不行了（注意：不是数据库里，在数据库后端是可以的，但云函数不行），如下：
db.collection(event.table).where( event.condition ).orderBy("上报时间", "desc").get() |
提示的是：

我知道应该尽量用英文，
我只是想知道的是fieldPath是一个什么样的对象，为什么不叫field，应该怎样构造出来，是否能够通过其他方式看到其他的fieldPath？
