Toys generally refer to items that can be used to play. Playing with toys is often used as a way of entertaining in human society.
Toys can also be natural objects, that is, non-artificial things such as sand, stone, mud, branches, etc. Toys should be understood in a broad sense. They are not limited to the things sold on the street for people to play with. Things that you can hear, hear and touch can all be called toys.
Toys are suitable for children, more suitable for young and middle-aged and elderly people. It is a tool to open the smart skylight and make people smart. 1. Items for playing games. Ming and Tang Shunzhi's "Reconstruction of Confucianism in Jingxian County": "Zhou declines, the king's way is abolished and lacking... The "Yi" image, "Spring and Autumn", the joy of the sixteen kingdoms, are only used to boast to the lords and guests, as antiquities toys, but have not been used to teach disciples ." The second episode of "Nie Haihua": "The strangest thing is that someone went to Shanghai to buy East and West Kit Kat toys and shipped them into Beijing."
2. This refers to something specially designed for children to play with. The first scene of Lao She's "Women's Clerk": "The small bamboo poles are surrounded by straw, and on them are simple toy windmills made by Grandpa Song, little roosters made of chicken feathers and stalks, etc." Bing Xin "A Year Away from Home" : "﹝ Zhen Xu brought a lot of toys, and a few children started to play with them, causing many college students to look around. With the continuous recovery of the world economy, the consumer demand of the toy market is also gradually recovering. The global toy market sales will reach 86.3 billion US dollars. North America and Europe are still the two largest toy consumption regions in the world, and they are also the world's two largest toy regions. While the United States imports 1/3 of toys, the EU imports 2 /3 are all Chinese products, and more than 2/3 of the products in the global market (except mainland China) come from China. China is an uncompromising toy manufacturing country.
The average annual growth rate of the toy manufacturing industry is 17.41%. By 2010, the sales revenue of the industry exceeded 100 billion yuan, and the profit was 4.142 billion yuan. By the end of 2010, there were 1,899 enterprises above designated size in the toy manufacturing industry, with total assets of 67.583 billion yuan and 673,500 employees.
With the appreciation of the RMB, rising prices of raw materials, rising labor costs, and increasingly strict foreign quality certification, the production costs of OEMs have risen sharply. Due to the lack of independent research and development capabilities of OEMs, the customer structure is single, and they cannot be distributed to toys in the fierce market. Businesses shift the rising cost, and profit margins are squeezed. The decline in the profits of OEMs has led to a low level of overall profits in the industry.
