主题：论鸿蒙 （序）先说结论 -- 大山猫

I have a "smart" oven, I can set up the temperature, cooking time etc. And when the time is up(ready to cook, or when the coking is done), I will get a notice on my cell phone. I can also interrupt or cancel a preset procedure.

Of course this doesn't need 5G os far , but think of things that may interconnect: smart windows, desk lamps, your bed etc
