On the way home after the light mountain climbing, there is a tree that is about twice as tall as the height of my height, which is full of red fruits. If you take a closer look, you will see a small apple-like fruit in the shape of a bell. Immediately take a picture with my smartphone and check it with Google Lens, it says “Zumi”. From April to June, flowers that look exactly like apples bloom, and it seems that they will bear fruit by this time. “桷” is also written as “酸実”, and when the fruit is ripe, it has a strong acidity, but when it frosts, it has a slight sweetness. And so when I put it in my mouth and chew it, it was sour and sour, and I spit it out of my mouth. However, it seems that it becomes sweeter when it is more ripe, and it can be jammed. Also, it seems that yellow dye can be produced from the bark, so it was a great learning experience.
