From 65438 to 0983, Zhang Haidi began to engage in literary creation, translated hundreds of thousands of English novels, such as The Beach Clinic, and compiled books, such as Windows Open to the Sky and Questioning Life and Dreams in Wheelchairs. Among them, Dream in a Wheelchair was published in Japan and South Korea, and Pursuing Life was published less than half a year and reprinted three times, winning the national "Five One Projects" book award.

Subsequently, Zhang Haidi became a moral force. Zhang Haidi is now a member of the Chinese People's Political Consultative Conference (CPPCC) and works in Shandong Writers Association, engaged in creation and translation. Zhang Haidi said: "I am like a meteor, and I want to leave the light to the world." With this ideal, she studied and worked with extraordinary perseverance and sang a hymn of life. "To live is to do things for the people." Zhang Haidi said so and did the same. 1970, when she was 15 years old, she followed her parents to live in the countryside. In the countryside, she thinks of others and works for people everywhere. She found that there was no music teacher in primary school, so she took the initiative to teach singing at school. After class, I also help students organize self-study groups, give them haircuts, button buttons and get dressed. She found that there was a shortage of doctors and medicines in the village, so she decided to study medical knowledge and technology, and used her pocket money to buy medical books, thermometers, stethoscopes and commonly used medicines. She has finished reading medical books such as Acupuncture, Human Anatomy, Internal Medicine and Practical Pediatrics. When learning acupuncture, in order to experience the sense of acupuncture, she practiced acupuncture repeatedly on herself. In just a few years, she actually became a young local "famous doctor".

Zhang Haidi encouraged Uncle Geng to enhance his confidence in overcoming the disease mentally, while reading a lot of books and carefully treating Uncle Geng. Later, Uncle Geng was finally able to talk and walk. At this time, Zhang Haidi deeply realized the happiness of serving the people. Comrade Zhang Haidi regards doing things for the society and the people as his greatest happiness. Her lofty spirit shines with the light of communism. Some people say that life is the happiest if you eat well, dress well and play well. I think the happiest thing in this world is to work hard, make a determined effort, create wealth with your own hands and contribute everything to the cause of human liberation-communism.

Question 6: The gravity of a black hole can suck light away. Does it mean that the speed of a black hole is faster than the speed of light because of infinite gravity, and even the fastest thing-light is attracted, so there is no way to escape the gravity of a black hole. Because even the light can't run away, the time around the black hole will gradually stop. You can watch the movie Interstellar if you are interested. It's really interesting.

Question 8: What's the meaning of black? Black is a color with many different cultural meanings. Black will never go out of fashion.
Color and light
Black can be defined as no visible light enters the visible range. Contrary to white, white means that all the light in the visible spectrum enters the visual range at the same time. If the pigment absorbs all the light in the spectrum and does not reflect any color light, the human eye feels black. If the pigments of the three primary colors are mixed in a proper proportion, and the reflected colored light is minimized, the human eye will also feel black. So black can be caused by insufficient light (night) or by absorbing all colors of light (black pupil).
