'''
将秒数转换为可读性更强的表述方式
eg:
```
In [4]: print seconds_to_human_readable(33)
33 秒

In [5]: print seconds_to_human_readable(60 * 3 + 2)
3 分钟, 2 秒

In [6]: print seconds_to_human_readable(3600 * 2 + 60 * 3 + 2)
2 小时, 3 分钟, 2 秒

In [7]: print seconds_to_human_readable(3600 * 24 * 3 + 3600 * 2 + 60 * 3 + 2)
3 天, 2 小时, 3 分钟, 2 秒
```
