I am afraid that all collectors of match trademarks are familiar with the small Swedish town of "Yencheping". It is located in the center of southern Sweden, and people are accustomed to calling it "the heart of Sweden". The 150-kilometer-long Lake V?ttern, the second largest lake in Sweden, is like a giant blue ribbon, maintained on the slightly raised hill at the northern end of the town. Swedish Match City-Swedish Match Museum is located on the edge of the vast blue lake. This is a two-story building. The ocher-red ridged roof and dark gray wooden wall structure seem plain at first glance. However, once you enter the museum, you will see a dazzling array of things to see and be quite distinctive. The surrounding walls are covered with various matchbox patterns and trademarks. Entering the movie hall on the left, the short 20-minute film clearly reviews the long history of mankind since drilling wood to make fire; it describes the hardships and hardships people suffered in making fire before the birth of safety matches: The match pocket would explode suddenly at some point. When the smoke cleared, the person had already fallen into a pool of blood, groaning in pain. In the center of the wall of the physical exhibition hall hangs a huge portrait of the father of the Swedish match industry - Johan Lundstyem and his brother Carl Lundstyem. As early as 1845, the Lun brothers rented a small workshop in Yancheping Town and began to produce phosphorus matches. Two years later, they established the country's first match factory where the museum is today. In the beginning, most of the production procedures were manual operations. For example, workers put matchsticks into the medicine tank to dip gunpowder by hand. As for the matchboxes, they were all made by hand. Nowadays, the scene of the whole family gathering around the table and pasting cardboard boxes has already entered the humorous genre paintings. In 1864, Alexander Lagman, a 28-year-old machinist, invented the first automatic match machine, which completed multiple processes at one time, from match production and feeding to finished product packaging. This behemoth that occupied half of the hall seems really stupid today, but once it was started, tens of thousands of matches were produced in a few minutes, thus ending the era when match production had always been manual operations. Since then, with Encheping as the center, Swedish matches have been sold throughout Europe and even around the world. In 1903, six match factories in Sweden were organized into a joint company, with their headquarters located in Yancheping. In 1913, eight emerging match factories headed by Ivar Kruger established a separate company with the intention of competing with the Yancheping Match United Company. However, soon after, they merged with it in 1917 due to lack of financial resources. Thus the Swedish Match Company was established, unifying the country and dominating Europe. The second floor of the museum is the world of trademarks. Match trademarks from different eras and countries are neatly arranged in the display cabinet. What is surprising is that there are three trademarks with the faces of Sun Yat-sen, Huang Xing and Li Yuanhong printed on them during the Chinese Revolution of 1911. The former King of Sweden, Faruk, was a world-famous collector. Once, he heard that a match trademark produced by Yancheping Match Factory was found in Denmark, so he took a special plane and flew to Copenhagen to buy it for 3,000 Swedish kronor. Buy it back; that was one of the earliest match brands produced by Yancheping, and it read: Sulfur-free Indoor Matches. According to statistics, so far, Sweden has exported more than 10,000 match brands overseas, and even more if domestic sales are included.
