Do you still remember Lu Xun's elementary school work "From Baicaoyuan to San Tan Yin Yue", which contains such a passage describing what I ate when I was a child? Now, no matter how I eat, things are still the same, but the taste will never be the taste in my childhood memory.
Memories of childhood often beautify the taste of things we like to eat. People don't always say "it's best not to get it", but they miss it very much because they have lost it. The snacks we ate as children taste different now, what's more, when we grow up and have more experience, the food we eat is mixed, the taste will change, and the familiar things will become strange.
In addition, the production process has also changed. When I was a child, things were often true. Nowadays, many things are cut corners. Some materials of mung bean cake have been replaced by similar things with similar tastes, which are no longer pure.
I hope it is useful to you, ~ (@ _ @) ~ a little feeling.
