Children are very sensitive about recognizing people. A two or three-year-old child can know dozens or hundreds of people, and literacy is the same. According to the theory of synchronous development of two languages put forward by Professor Feng Dequan, the father of early education, auditory language and visual language can develop synchronously. Learn to read like you learn to speak. When learning to speak, you can write out the words for your children, so that they can be read easily in an environment. Teacher Qiu Dehui's son recognized more than 100 at the age of one. A parent spends half an hour reading with his children every day and insists on this method. His son was already reading Zi Tong Zhi Jian when he was in the fifth grade of primary school. Flash teaching can be used in card literacy. Flash literacy is a better integration of hearing and vision, and literacy can be started as early as 6 months in advance.
