The strength of teenagers depends on the strength of young children, on the country, and the way parents educate depends on social concepts. When the country is strong, the educational methods are more standardized, which is more conducive to cultivating talents who go abroad.
So it is right to imply that the country itself is strong and powerful, but I see that this view was put forward long before I answered the Lord.
There is no direct relationship between the strength of teenagers and the progress of the country. A strong country leads to a strong teenager, and a strong teenager makes a strong country.
The development trend of the country is inevitable and unchangeable. If a country's thinking is not advanced enough, its young people will not have strength beyond the scope of a powerful country.
The so-called economic development and strength growth are just the evolution of the times. Your country is prosperous, and so are other countries.
