Lullaby, lullabyThere were some lullabies that were said to make people fall asleep easily, such as Jia Tao and Dai Yuzhe's "Lullaby"(released in 2013); Chen Li's performance of a masterpiece written for "hypnosis";;; Bach's "keyboard etude consisting of an aria and its variations, composed for a harpsichord with two keyboards". This piece was in the form of a variation, with 32 pieces, and the theme was the solemn and noble Sarabander dance "Aria". There was also the world-famous hypnotic song "Weightless" and the deep water lullaby from Alpha Brainwave music.

Schubert's Lullaby"Lullaby" was one of the famous masterpieces of the Austrian composer Schubert.
Schubert had composed this piece of music at the age of 19, based on a poem by Claudius. At that time, he was living in poverty, and the background of his creation stemmed from an accidental experience. One night, he wandered the street hungry, trying to borrow money to satisfy his hunger. After failing, he entered a luxury hotel and saw a small poem on the old newspaper on the dining table: "Sleep, sleep, my dear baby, mother's hands gently shake you..." This simple and touching poem moved him, making him think of the image of a loving mother, which inspired him to create a lullaby. He handed the song he had written to the restaurant owner. Although the owner did not understand music, he felt that the song was beautiful and gave him a bowl of braised beef with potatoes.
In terms of artistic characteristics, the melody was simple and pleasant to the ear. The range was not large (only nine degrees). The structure was "rise, multiply, turn, and combine". It was composed of four phrases and repeated three times to express the artistic conception with different lyrics. The cradle was shaken by adding notes, and the decorative notes were added to express the release of emotions. The rhythm was stable and the rhythm was four to four. The lyrics depicted the scene of a mother coaxing her child to sleep late at night, full of maternal love. This song was soon sung all over the world and was now well-known by everyone.
The original work was equally exciting. You could click on the original work of "The Story of Rose" to understand the plot in advance!
100% lullabyThere was no song that could guarantee that it would make people fall asleep. However, there were some songs that were thought to have a very good hypnotic effect. For example, Bach composed a variation for Count Catherine. This was to help the count who suffered from insomnia. It was in the form of a variation with 32 pieces. The theme was the solemn and noble Sarabande dance " Aria " with a soothing melody. There was also the world-famous hypnotic song, Weightless. It was said that very few people could listen to the complete song while awake. In addition, the deep water lullaby of some Alpha brainwave music could also be used to help sleep before going to bed. The 5-minute essence version of it could be placed at the bedside to help sleep. During the Spring and Autumn Period and the Warring States Period in China, there was a discussion about the influence of music on physical and mental health. Music could play a psychological suggestion effect similar to hypnosis by adjusting emotions. Some soft and soothing rhythms might help sleep, but different people's reactions to different music were different, and it was impossible to guarantee 100% sleep.
Children's songs, lullaby lyricsHere are some lullaby lyrics for children aged 0 - 3:
- Twinkle T The star blinked its small eyes and twinkled until dawn. It was not a small star, but a firefly flying in the night sky. Tick tock.
- "Worms Fly"(Classic children's song, can be used as a lullaby).
- And oh, furry doze doze; oh, furry doze doze. Mao Wa, Mao Wa, you are sleeping. There is a nest of birds on the tree, green pants, red jacket, a flower hat on the head, a grass waist on the body, etc.(Different regions may have different versions of the description).

What's that lullaby in Tom and Jerry?The lullaby in Tom and Jerry was "Rock a bye baby." In addition, the animation also involved music related to lullaby such as Brahms's "Brahms: Lullaby."

4G slowed down in the middle of the nightThe slow 4G network speed in the middle of the night could be due to a variety of factors. On the one hand, even in the middle of the night, there may still be more users using the 4G network in some areas. When the traffic pressure on the 4G network is high, the network speed will slow down. On the other hand, the signal problem of the base station in the area might also affect the network speed. In addition, if you were using the " Speed Limit " package and the traffic limit was used, the network speed would also slow down. It is recommended to avoid high-load operations such as large downloads and online videos when the network speed is slow. You can try to contact mobile customer service for further investigation and resolution.

Instead, the transition animation slowed downIf the transition animation is slow, it may be related to the following factors in the front end development:
** 1. About the transition of the CSSs **
1. ** Unoptimized transition attribute settings **
- If the transition attribute is set for transition effects (such as displacement, rotation, etc.), but the transition time, delay time, or transition function (such as ease, linear, etc.) are not set properly, the animation may be slowed down. For example, if the transition time was set too long, the animation would look slow. For example, if you set the transition time of an element to 5 seconds, the animation speed would be significantly slower than if you set it to 0.5 seconds.
- When setting up a transition for multiple attributes at the same time, if the transition parameters of each attribute were not adjusted specifically, the overall animation effect might not be good. For example, if you set up a transition for the width, height, and clarity of the elements at the same time, and the width and height changes are large, and the transition time is long, it may make the animation seem slow.
2. ** Element layout and performance impact **
- If the layout of an element changes complicatedly during the transition, such as an element changing from absolute positioning to relative positioning, or the size of the parent element changes during the transition, this may affect the performance of the transition and cause the animation to slow down. This was because a change in the layout might cause the browser to rearrange, and rearranging would consume more performance.
- When the elements that are being transitioned contain a large number of sub-elements or are deeply embedded, the browser needs to deal with more element relationships when calculating the transition effect, which may also cause the animation speed to decrease.
** 2. Javelin animation (if involved)**
1. ** Problem with the timer **
- If you use setTimeOut or setDuration to control the animation frame update, because they are not specifically designed for animation, they may not be able to accurately update the animation frame according to the browser's refresh rate, resulting in the animation not smooth and looking slow. For example, in a complex javelin animation, using setTimeOut to update the position of the elements, and the time interval set is not reasonable (such as the time interval is too long), will cause the animation to be stuck and slow down.
2. ** Complicated logical calculations **
- In a javelin animation, if every frame of the animation required a lot of logical calculations, such as complex mathematical operations or frequent query of the attributes of the DOM elements, it would take up a lot of computing resources, causing the animation frame update speed to slow down, making the entire animation look slow.
** 3. Device-related aspects (if it is on a specific device)**
1. ** Device Performance **
- If the device's processor performance was low and there was insufficient memory, it might be difficult to process the animation effect, causing the transition animation to slow down. For example, when running complex animation effects on some older mobile devices or low-end computers, the animation would show obvious delays and slowness because the hardware of the device could not quickly process the changes in the image.
2. ** System settings **
- On some devices, the system settings might affect the speed of the animation. For example, if you turned on the "reduce dynamic effects" on an iOS device, the animation would use the fade-out effect instead of some more complicated zooming or slideshows. This would change the way the animation was presented, and it might look slower or simpler. On Android devices, similar system-level animation settings (such as animation zooming ratio, etc.) would also affect the speed of transition animation.
