On December 4, 2013 (November 2, 2013 in the lunar calendar), China's abacus application was successful. On the evening of December 4, 2013, after passing UNESCO's review, the abacus was officially included in the List of Intangible Cultural Heritage of Humanity. This is the 30th project listed as intangible cultural heritage in my country. China is currently the country with the largest amount of intangible cultural heritage in the world. Previously, UNESCO once introduced that abacus was a major invention in ancient China, and the China people went through a long period of more than 1800 years. It is known as "the oldest computer in the world" for its simple computing tools and unique mathematical connotations. In January 2009, China's abacus applied for the United Nations "Representative List of Intangible Cultural Heritage of Humanity." However, the application for the heritage was not successful at that time. The China Abacus Association revised the application materials several times until good news came last night. Su Jinxiu, vice president of the China Abacus and Mental Arithmetic Association, told a Xinhua Agency reporter after the successful application for abacus that with the development of computer technology, the computing function of abacus has gradually been weakened, but the ancient abacus still has tenacious vitality. Today's successful application for abacus will help more people understand and understand abacus, enhance national pride, and attract more people to join the ranks of promoting and protecting abacus culture. Abacus is a method of numerical calculation using abacus as a tool and is known as the fifth largest invention in China. As early as 2008, after review and approval by the State Council, abacus was included in the second batch of China's national intangible cultural heritage list. Current situation: Abacus was cleared out of primary school textbooks ten years ago until the 1990s. Abacus was still a part of my country's primary school mathematics teaching syllabus. However, in the "Compulsory Education Mathematics Curriculum Standards" issued by the Ministry of Education in 2001, Abacus was cancelled. The reason is that the calculation function of abacus has been replaced by calculators, and abolishing abacus teaching can also reduce the burden on students. In addition, abacus was once a compulsory subject for accounting study, but this is no longer the case. "It used to be because of the need for accounting qualification certificates, but now the policy has changed. Therefore, students majoring in accounting in colleges and secondary schools rarely learn abacus,"said Ms. Zhang of the Shanghai Abacus Association. According to Ms. Zhang, since last year, some national accounting competitions have also cancelled abacus projects. "At the grassroots level, whether it is teachers in colleges and universities or the society, they still support abacus." She said that due to administrative orders and policy guidance, such as the fact that computerization of accounting can replace abacus, abacus teaching has encountered some resistance. Application: Promoting abacus can improve the intelligence of old and young people. According to reports, there are currently four categories of groups for the promotion of abacus: young children, children with intellectual disabilities, the elderly, and students from colleges and universities. Ding Xianjue, president of the China Abacus Association, said that it is now possible to apply abacus skills to the teaching of children's abacus and mental arithmetic. "Scientific research has proved that abacus can enhance children's memory and attention." "A large amount of scientific data can prove that abacus can develop children's intelligence. Abacus is not a simple computing tool and can develop children's intelligence,"Ding Xianjue said. Ms. Zhang introduced that the Shanghai Abacus Association has conducted experimental education on abacus in a Kangjian school for 16 years. "Abacus can develop the left brain of children with intellectual disabilities and improve logical thinking." Ms. Zhang introduced that because the children's conditions are different, the effects are not the same, but overall the results are good. "The elderly prefer abacus, which is very helpful for the elderly to brain and prevent Alzheimer's disease." Ms. Zhang said that at present, the Shanghai Abacus Association offers a two-handed abacus course for the elderly, and uses textbooks to teach the elderly. (Beijing News reporter Li Dandan) Extended reading: Abacus is known as the fifth largest invention in China Extended reading: Abacus is known as the fifth largest invention in China. Abacus is a method of using abacus as a tool for digital calculation. It is known as the fifth largest invention in China and has previously been included in the list of national intangible cultural heritage in China. Su Jinxiu, vice president of the China Abacus and Mental Arithmetic Association, told a Xinhua Agency reporter after the successful application for abacus that with the development of computer technology, the computing function of abacus has gradually been weakened, but the ancient abacus still has tenacious vitality. Today's successful application for abacus will help more people understand and understand abacus, enhance national pride, and attract more people to join the ranks of promoting and protecting abacus culture. In the future, abacus or returning to primary school classrooms has learned that abacus has long since faded out of the scope of teaching in universities and compulsory education, and even accounting students in universities in our province rarely learn abacus. However, in the new curriculum standards for 19 subjects and subjects in compulsory education announced by the Ministry of Education in 2012, the requirement of "knowing that an abacus can represent multiple digits" was added to the understanding of numbers in grades 1-3. This may be a sign that abacus is back in primary school classrooms. Li Yi, a professor at the School of Economics and Management at East China Jiaotong University and a PhD in accounting, believes that it is not necessary for universities to offer abacus courses, but it is still necessary for students to learn abacus in primary school. "Abacus can improve students 'understanding of numbers and improve hand flexibility, which is beneficial to children's brain development. ¡ö Chovqan, an intangible cultural heritage event selected at the same time, is a traditional Karabakh equestrian competition in the Republic of Azerbaijan. It is held on the grass and is held in two competing teams, each team consists of five riders riding Karabakh horses. The players held wooden bats and drove a small leather or wooden ball into their opponent's goal. The competition was accompanied by a folk instrumental music called "janghi". Paach Ceremony A grain worship ceremony held in San Pedro Sacatepecos. The entire ceremony describes the process of growing and harvesting the grain, including dances, Maam prayers and meals. Elderly men and women dressed in ceremonial costumes with corn whiskers, said prayers in consciousness, helped with preparations and provided food, and performed ceremonial dances to music played on a marimba.
