Now there are a lot of international students in our country. They come from all over the world, or from Britain, France, Germany and other countries in Europe, or from Tanzania, Zambia, Ghana and other places in Africa. There are also many neighboring countries such as Japan, South Korea and Russia. It can be said that all the international students in our country have gathered together to embody the "global family" vividly. And many overseas students are advocating the things of Zhong people, such as high-speed rail, such as mobile payment. Therefore, there are many interviews with foreign students to introduce some "Zhong national artifact". Among them, a "Zhong national artifact" has been popular overseas for many years, but few people know it, which also surprised foreigners. It turns out that they have been relying on "made by Guo" for a long time.

　　This thing is "mosquito swatter". I believe that people in China are also very confused. After all, few people will notice this thing, and this thing is not so hot even now. Because of the rapid change of mosquito repellent products, mosquito swatter has been hot for a long time after the new millennium, but now it has disappeared. However, no one thought that the anti mosquito photos had already transferred to foreign countries. According to the interview with foreign students, no matter in the developed countries in the west, in the developing countries in Southeast Asia, or in Africa, many foreign students are familiar with the "mosquito swatches" put forward by the interviewers, and they also say their own mosquito swatches in succession, but most of them are from grandma's generation. After careful understanding, they found that the mosquito swatches in their families are from China In fact, the "anti mosquito swatches of Zhongguo" purchased in human commodity stores have already been sold all over the world.

　　In fact, it is said that the inventor of this thing is the Taiwanese of our Guo, named tsa-i Shih's Taiwanese made this tool to shock mosquitoes and flies with the electrostatic field between power grids in the 1990s. In 1996, they were authorized to apply for the US Patent No. 5519963. However, it was also said that Gan Hancheng, an inventor in Nanjing, Jiangsu, China, applied for a patent in 1991. No matter what kind of patent, this unknown thing began to become popular all over the world. At one time, the mosquito swatter was considered as a "magic device for mosquito control", so many Chinese Guo manufacturers have involved, and most of them are Chinese Guo still manufacturing this thing, and have successfully made this thing throughout the world. Maybe Europe, America and other places are not so popular now, but in Southeast Asia and Africa, where mosquitoes are rampant, the business of mosquito swatters is still hot. For example, it's autumn, Southeast Asia is still experiencing dengue fever, so there are many Chinese Guo enterprises with UL certification, which are also exported to these countries to contribute to the mosquito control industry.
