How's Wang Xifeng's figure? Video

In the different versions of 'Dream of the Red Chamber', the figure of the character played by Wang Xifeng was different. Deng Jie, who played Wang Xifeng in the 87 edition of Dream of the Red Chamber, was described as dark-skinned and petite during the casting. As for Lin Peng, who played Wang Xifeng in the movie " Dream of the Red Chamber: The Golden Fate ", there was no specific description of her body. During the casting competition for the role of Wang Xifeng, Le Yun was tall and slender, and Zhou Yue was also good-looking and tall. This indirectly reflected that in the eyes of some creative teams, the role of Wang Xifeng might have a consideration in terms of figure, but this was not the same as the final figure of the actor who played Wang Xifeng. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

What if I can't get pregnant at 45?

Being unable to get pregnant at the age of 45 may be caused by many factors. It can be solved from the following aspects: 1. ** Inspection ** - Check the function of the ovaries to see if they are ovulating normally. Because the function of the ovaries of a 45-year-old woman is declining, the number of eggs is reduced, and the quality may be poor. - Check the environment of the uterus to see if there are any problems such as sticking or fluid accumulation. - Check if the fallopian tube is unobstructed. Even if only one side of the fallopian tube is unobstructed, there is still hope of pregnancy. In addition, B-ultrasound and hormonal examinations could also be performed to check if there were any factors that might cause infertility such as gynecology inflammation. 2. ** Healing ** - For the case of infertility caused by fallopian tube, gynecology inflammation, etc., the cause can be treated after the cause is identified. If one was unable to conceive naturally due to advanced age, test-tube babies were a method that could be considered, but test-tube assisted pregnancy might not be able to completely overcome the age limit. 3. ** In terms of pregnancy preparation ** - In terms of living habits, she should maintain a good schedule, go to bed early and get up early. She should avoid staying up late, smoking, drinking, and other harmful behaviors to the ovaries and uterus. - It could improve the body's resistance and immunity, promote metabolism, and enhance the function of reproductive organs such as ovaries and uterus. - In terms of diet, supplement nutrition, eat more foods rich in protein, and eat a light diet. Eat less spicy food. - Psychologically, she had to adjust her mood and not be too anxious. She had to let nature take its course and avoid too much pressure, because emotional fluctuations could affect pregnancy and the condition of the fetus during pregnancy.

What is beyond the world?

If the " world " here referred to the universe, there were many views about the universe: 1. Outside the universe might be an unknown dark space. Because the universe had a lifespan and the Big Bang had not expanded to the border area, this outer space might not exist. 2. There might be other universes. Some people believed that the outside world was an extremely vast hyperspace that contained countless universes, such as parallel universes. According to quantum theory, the different consequences of an event would form a universe. The scientists also found some evidence through cosmic microwave radiation, such as the friction marks of a universe being hit by another universe. The development of quantum mechanics also increased the credibility of this view. 3. There was also a speculation based on civilization. The outside of the universe might be the laboratory of an advanced civilization. Everything in our universe was arranged by an advanced civilization, which was why it seemed so orderly. In addition, from some specific theories: 1. The infinite universe theory believed that the universe was infinite, and the observable universe was only a small part of it. There might still be similar structures outside the observable universe. For example, there might be another Earth with the same history, civilization, and human development history far away. 2. The dual-universe theory proposed that the two-universe model was derived from the dissimilarity of antimatter and antimatter. In the other universe, antimatter was more than antimatter, and it was a twin universe dominated by antimatter. 3. The bubble universe theory believed that each universe was like a bubble. Different bubble universes had different physical parameters, and the collision between bubble universes would form a new universe. 4. The Big Bounce Theory deduced from the theory of circular quantum gravity that the universe was a periodic process of continuous explosion, expansion, and contraction. The universe in each cycle could be a parallel world of the previous cycle. 5. The multi-world interpretation believed that the quantum superpositions of microscopic particles could produce different parallel worlds after the collapse of observations. If the " world " here did not refer to the universe, but the world in the sense of Earth or human society, from the perspective of science, the space outside the Earth was cosmic space, including other celestial bodies in the solar system and galaxies outside the solar system. From a philosophical or abstract point of view, different philosophical systems or cultural backgrounds had different explanations. For example, in some religions or philosophical thoughts, the world outside may be a space of existence on the spiritual level, but this lacked scientific basis.

A novel that mistook demons for angels

I recommend Descending of the Abyss of the Heavens. This book is extremely dark. The main character was reborn as a demon, spreading the seeds of evil in thousands of planes, tempting people to fall and become the ruler of the Abyss. In the first few chapters, the main character still had some humanity, but in the later chapters, he completely demonized, which was extremely in line with the Dark Style. The writing was a little tender at first, but it improved later. The dark scenes were bloody. It was just that the update made people speechless. Although there was a plot that abused the main character and the beginning was a little toxic, the end was super exciting. The main character was cold and bloodthirsty. There was no female lead. He was cautious and was afraid of being 404. However, he was really good-looking. There was also " Chasing Dreams Chinese Entertainment ", which told the story of Chinese Entertainment in the late 1990s. The protagonist's journey from running errands for the crew to becoming the best actor and then becoming a director. " The Final Demon of the Abyss " was not bad either. It was set in a world similar to the world of DNT. The main character was a demon. The story took place in a world of swords and magic. Humans were abandoned by the gods, and the rise of demons changed everything. " American Manga: Something's Wrong with This Superhero World " was very creative and subverted the superhero image. " Going Back to the Wilderness, I Want to Verify the Origin " was a Xianxia genre. The main character went back to the Wilderness to rewrite myths and seek Dao. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Harry Potter Transgender

Some fans imagined the situation after the characters of Harry Potter changed their genders. For example, after Harry Potter became a woman, his enemies might not be able to bear to kill him because of his good looks, and the plot of tormenting her might disappear. Hermione Granger became a man, and everyone might bow down to her because of her talent. Ron Wesley became a girl, and she might be regarded as a brainless person. Draco Malfoy became a woman, and she might become a spoiled girl because of her rich family. Cho Chang became a man, and she might pursue Harry Potter. Sephalus Snape may still fall in love with Lily Potter as a woman, but only as a friend, and the story will be rewritten; Voldemort may be questioned as a woman, why not be a housewife, and it is difficult to find accomplices to become Voldemort. However, this was just the fantastical content of the fans. If the gender was really set in this way, the whole story would have a huge reversal. Harry Potter and the Goblet of Fire was not enough.
