What is the relationship between the four ancient units of measurement: stone, bucket, ascending and merging?

Stone, bucket, ascending and closing are four units used to measure the volume of solid particles in ancient times, and the conversion relationship between them is decimal. Simply put, one stone equals ten buckets, and one hundred liters equals a thousand combinations. It's like the most common thing in our daily life. One meter is equal to ten meters, and one hundred centimeters is equal to one thousand millimeters, but this meter, decimeter, centimeter and millimeter are units of length, and this stone, bucket, liter and combination is only unit of volume.

Speaking of this, I still remembered that when I went back to my hometown a few years ago, I saw rice and flour in a small shop in my hometown, and even grain and oil, soy sauce and vinegar were sold in some old ways. Among them, I am most impressed by two things. One is that they still use "stone" as the unit of measurement for the elderly when asking about food, and the other is that they still use "lift" as the elderly when selling grain and oil.

In addition, they will also put up slogans such as "Weigh the scales and strive for fullness" on the wall to mark the management norms of their grocery stores. However, it is inevitable that people from the same town will come and tell us outsiders that some businesses are so tricky that when we want to buy things for our relatives at home, we will either bring them from the city or find a familiar child to buy them for us. Of course, it seems that this is a bit tricky now.

Of course, inspired by this little anecdote, I also remembered an opening poem that Degang Guo said, that is, the sentence "The cart bears the burden of life" written online. I have doubts about this, because whether in Governor Shanglang or Notes on Wei Caotang, I smell four, the burden of stone represents a grain of stone, so I am shallow.

It can be seen that this stone, bucket, rising and closing are not only four units used to measure the volume of solid particles in ancient times, but also have more and deeper meanings in them, waiting for us to explore slowly.
