Of course, you can join. Its ancestor is American McCullough. 1938, American mccullough tried to make new ice cream products. 1940, the first Dairy Queen ice cream shop opened in Joliet, Illinois, USA. Because the founder Mr. mccullough likes to call cows the queen of dairy industry, the ice cream shop got its name. This is today's Dairy Queen. DQ has opened nearly 8,000 chain stores in 25 countries since the first ice cream shop opened in summer of 1940. It provides Dairy Queen ice cream, Orange Julius fresh fruit dew, Karmelkom popcorn and other snack foods. It is the world's number one soft ice cream expert and one of the global chain fast food giants. DQ's ice cream is soft ice cream. After being evenly stirred, it has the reputation of not spilling the cup. At the same time, the fat content of DQ soft ice cream is only 2%, which is one sixth of that of ordinary ice cream, and it has three characteristics of low fat, freshness and health. It is amazing that the star product can still pour the cup without spilling it during the snowstorm, which is not available in other ice creams.
