We've all had the experience of walking in the cold rain.
Whenever this time I will complain to hold the umbrella,
because my hands have to be exposed to the cold air. So
I thought why not let the umbrella become a heating tool
and design this novel umbrella. In this umbrella, a heating
device is combined into the umbrella, supported by an
external rechargeable power. I hope this umbrella will
bring the warm feeling to the people who walk in
the cold rain.
