What's the way to distinguish between normal years and leap years and age?
** I. How to differentiate between normal years and leap years by year ** 1. ** General situation ** - If the year is not a hundred (that is, there are not two 0s at the end of the year), determine whether the year can be divided by 4. If it can be divided by 4, it is a leap year; if it cannot be divided by 4, it is a normal year. For example, 2016 was a leap year because 2016 div4 = 504 and there was no remainder. In 1987, 1987 div4 = 496…3. There was a remainder, so 1987 was a normal year. 2. ** Special circumstances (100 years)** - When the year was in the hundreds (such as 1800, 1900, 2000, etc.), it was necessary to determine whether the year could be divided by 400. If it can be divided by 400, it is a leap year; if it cannot be divided by 400, it is a normal year. For example, in the year 2000, 2000 + 400 = 5, and there was no remainder, so 2000 was a leap year. In 1900, 1900 + 400 = 4…300. There was a remainder, so 1900 was a normal year. ** 2. Method of Calculating Age ** 1. ** Year ** - The actual number of years from the date of birth to the current date. For example, if a child was born on March 1st, 2010, until March 1st, 2024, the actual age would be 2024 - 2010 = 14 years old. If the current date was October 18, 2024, then the child's actual age was still 14 years old (because it was not yet the next year). 2. ** Virtual year ** - From the time the mother became pregnant, it was usually one or two years older than her actual age, depending on local customs. Take the child born on March 1st, 2010 as an example. If the local virtual age was one year older than the actual age, then on October 18th, 2024, the virtual age would be 15 years old. 3. ** Calendar Age ** - The number of days from the date of birth to the current date divided by 365 days (normal year) or 366 days (leap year). The calculation required an accurate count of the number of days and then the calculation. 4. ** Bone Age ** - The development of the child's wrist bones was measured through X-rays to assess the child's actual age. This method was mainly used in the medical field. Age was determined based on the development of bones, and it had little to do with the actual year of birth. Read more exciting novels for free

A Simple Way to Distinguish Jadeite
Here are some simple ways to identify jade: 1. [Weight: Jade has a certain weight. If it feels too light, it might be fake.] 2. ** Judging by color **: Natural jadeite color distribution is natural and layered, while dyed jadeite color distribution is unnatural. It may be distributed along the cracks, like capillaries, and the dyed color often has no "color root", which appears "dead" and "stunned". Green jadeite was best with tender leaves, dark green was better than light green, and all-over green was better than partial green. Green was the best for jadeite, followed by purple, cyan and red, and black and "cat shit color" were the worst. 3. [Listen to the sound]: Gently tap the jade and judge by the sound. 4. ** Violet Light **: Illuminate the jade with an ultra-violet lamp to see if there is a fluorescent reaction. 5. ** Look at the luster **: Natural jadeite has a natural luster, but the luster of jadeite after acid corrosion will be affected. 6. ** Internal structure observation **: - Look at the "fly wings". This was the reflection of the jadeite mineral cleavage surface on the surface of the jade, similar to the wings of a fly. It was one of the green characteristics of jade and a unique symbol to determine whether it was real or fake. It was usually needle-shaped, pillar-shaped, or sheet-shaped. - Looking for the "orange peel effect", the orange peel effect of the natural jade A was that on the polished surface, there were bumps and dents of different sizes and directions similar to orange peel, and the boundary between the bumps and the dents was a gradual smooth transition. On the other hand, the jade B would have acid corrosion patterns, which showed that the bumps and dents were not smooth transition, but separated by cracks, like a spider web crack pattern. - Checking the impurities in the jade, it was inevitable that there would be impurities in natural jade. The lower the quality, the more impurities there would be. However, the jade corroded by strong chemical acid had fewer impurities and looked very clean. 7. ** Check certificate **: Check whether the jade has an identification certificate issued by an authoritative organization. 8. ** Rubbing and Absorption Test (for reference only)**: After rubbing jade on a towel, it will come into contact with small paper scraps. If it can absorb paper scraps, it may be fake because fake bracelets may have been filled with glue. After being corroded by strong acid and injected with industrial glue, friction will easily produce static electricity to absorb paper scraps. Natural jade is not easy to produce static electricity and cannot absorb paper scraps. The novel "Ledge" is equally exciting. Everyone is welcome to click and read it!

Is it normal to be a general at the age of 40?
Among the founding generals of New China, there were many who became generals around the age of 40. This had its specific historical background and personal factors, so it was normal at that time. From some examples, General Liu Zhen was awarded the rank of founding general at the age of 40. He was born into a poor family, but he joined the revolution when he was young. At the age of 15, he joined the Red Guards, then joined the Red Army, and at the age of 17, he joined the China Communist Party. He was promoted by virtue of his outstanding military insights, such as making suggestions for improvement after the Battle of Luotian. He was gradually promoted during the Long March and demonstrated outstanding military talent in the Battle of Lingongdu in Suqian. This meant that in times of war, young and capable people could become generals through continuous display of their own abilities, military talents, and contributions to the revolution. In addition, the average age of the founding generals in 1955 was 45.6 years old. Xiao Hua, Chen Xilian, and others also received the rank of general at the age of 39 and 40. This showed that in the course of the revolution at that time, it was possible for young generals to become generals at the age of 40 after experiencing the baptism of the Red Army, bearing the pressure of the war, and making contributions. However, in times of peace, it was relatively difficult to become a general at the age of 40. For example, in the 1970s, there was no retirement mechanism. There were many old officials, and the promotion of new officials was slow. Even if one could become a division commander at the age of 40, it was already very outstanding. For example, Song Qingwei was already a very low proportion of the division political commissar at the age of 40 in the military region. If he was promoted from a division commander to a military commander, he would be considered inexperienced and promoted too quickly. Therefore, whether it was normal to become a general at the age of 40 depended on the background of the era. It was a normal phenomenon in the special environment of the war era, but it was rare in peaceful times. The novel " The General's Promotion " is equally exciting.

Is it normal to be a general at the age of 40?
According to the reference materials, many generals held important military positions and became senior generals such as generals at the age of 30 - 40.
