Tobacco is one of the greatest public health threats the world has ever faced. Nearly 8 million people are killed by tobacco each year. In China, more than 1 million people die from smoking-related diseases every year.Thus, the Chinese government attaches great importance to tobacco control. In 2016, the CPC Central Committee and the State Council issued and implemented the outline of the "Healthy China 2030" Plan. In June 2019, the State Council issued the "Healthy China Action (2019-2030)", in which the "Tobacco Control Action" clearly stipulated the goal of "reducing the smoking rate of people over 15 years old to 20% by 2030".
