3 days cold...

There is an expression word in this season.
三寒四温 [San Kan Shi On].
「三」means three.
「寒」means cold.
「四」means four.
「温」means warm.
It means 3 days cold and then 4 days warm.
Actually,this is a old the northeast of China and Korean peninsula word for the end of autumn to winter.
Siberia high atmospheric pressure makes this weather.

As for Japan,we use it for winter to early spring.
I think it's very good expression.
Because,in this season,the temperature swings wildly from hot to cold.
In fact,last weekend were quite hot day although now it's cold...
But,I feel that spring has been coming until here. haha.

I've just seen that a news programme said some cherry blossom come out in Kochi prefecture!! Wow!!
