There is a jujube tree in my home, which used to bear good dates. After drying, it was found that there was no meat in the dates. What happened?

The drying method of jujube should be determined according to different varieties. Since your family didn't do well only this year, it means that the key is not "doing".

I think this is why dates are picked before they are ripe. This year's dates ripen one solar term later than in previous years, so if you date according to previous years' experience, there will definitely be a phenomenon of not drying. Note that dates are not played when they are all red, but when most dates begin to "sugar heart". The so-called candy heart is to bite the jujube open and the pulp in the middle has begun to turn red.
