Lai Guishan, a young man, bought Zhou Bingheng's old winery in Maotai Town and renamed it Hengxing Winery after obtaining a lot of money through investment and operation. He used the recipe left by his ancestors and the skill of making Mao liquor, and with reference to scientific methods, he developed the winery from the original four wine cellars to twenty-eight new cellars, and then changed the new cellars into old cellars, which greatly improved the quality and output of liquor produced by Hengxing Burning House. By the eve of liberation, the annual output of the winery operated by Lai Guishan had reached 300,000 Jin, ten times more than that of Hua Mao. Later, Lai Guishan named the liquor produced by Hengxing Distillery "Lai Mao" after his own milk name, and personally designed Lai Mao's "Pengqiu Trademark". Since then, Lai Mao has officially entered the market, and under the careful management of Lai Guishan, Lai Mao enjoys a worldwide reputation.
Later, because "Lai Mao" attracted more and more attention, a large number of wineries labeled their liquor as "Lai Mao". For a time, the market was full of all kinds of "Lai Mao", and it was impossible to distinguish the authenticity. In order to distinguish the traditional "Lai Mao wine" from other brands on the market, Lai's descendants renamed the "Lai Mao wine" brewed by Lai Guishan's original craft as "Lai Guishan wine", which traced back to the original.
