The three golden heads of Guilin are Mr. Zou Jieming. Guilin Sanjin's avatar is Mr. Zou Jieming, chairman of Sanjin Pharmaceutical and a traditional Chinese medicine expert with outstanding contributions to the country. Mr. Zou led the scientific research team to tackle key problems for 8 years, breaking through the bottleneck of traditional frost making that is time-consuming and labor-intensive and with a low frost collection rate, and achieving a new breakthrough in the watermelon frost making technology. On the basis of retaining the magical effects of ancient recipes, it has also been adapted to the modern era. Due to the needs of industrial production, this technology won the third prize of the National Science and Technology Progress Award, and his portrait was used as a trademark as a commemoration.
