Guangdong Shuangxi has about 15 base units in China, which are distributed in major tobacco-producing areas, such as Liangzhou in Sichuan and Qujing in Yunnan. Tobacco leaves can only be said to be produced in Luoping, Pingdingshan and Nanxiong. As a brand-oriented base unit, the tobacco leaves produced are only used by one cigarette industry, so Double Happiness has nothing to do with China.
