The fertility rate of Europeans has been declining in recent years.

According to a recent survey, fertility rates in many European countries are currently at the lowest levels in the world. Fertility is the average number of babies born to women of childbearing age between the ages of 15 and 49. The average woman of childbearing age in Germany now has only one baby, while the fertility rate in Russia is per person, and in Greece it is even lower, with only per person, which is much lower than the global average.

Italy's birth rate has been declining at the highest rate in the world for many years, and the current fertility rate is only human, thanks to the high fertility rate of immigrants.

In the past, European countries were the richest countries, but they also had small populations, but now they continue to decline, and I think it is because they don't pay attention to the fertility rate, thinking that they are good if they are rich

I recommend you to take a look at Linda's "Take a Book to Paris" and "Spanish Travel Notes", which talk about European architectural scenery according to history and humanities, which is very interesting.

I really don't know about this, I haven't paid attention to it.

Keep it and use it to make your own equipment later. Now that you've sold it, you'll have to take someone else's when you want to use it to make equipment in the future. Because after your level is high, you can't play low-level materials. Unless you're willing to open another trumpet to play materials.

Copper, plain yarn to the back is the most expensive material for production. Believe me to keep it for the stall to sell later, and put it in the trumpet first.

The production of material materials provides human beings with basic means of life and survival, such as food, clothing, housing, and transportation, and is the most basic practical activity of human beings. Production activities are the foundation for the existence and development of human society and the most basic practical activities of human beings.

"If any nation stops working, it will perish not only for a year, but also for a few weeks" (Selected Works of Marx and Engels, vol. 4, p. 368), and all other social activities of mankind are based on the production of material materials, and change with the development and change of the mode of production.

1. In order for human beings to survive, they need to have the most basic material means of subsistence, such as food, clothing, and housing, which can only be obtained through the production of material materials.

2. Material production activities are the prerequisites for human beings to engage in various other social activities.
