Black Swan Cake is the top cake brand launched by Holiland Group, a domestic baking enterprise, and it is also the top cake in China that the group has made every effort to build. On October 1, 2111, the first black swan store in China opened in wanda plaza, Hongqi Street, Changchun. Since then, Tianjin, Shenyang, Beijing and other cities have also opened stores.

Black Swan's well-paid takeout staff should be over 1.81cm tall and bilingual, and should be between 18 and 23 years old. The black swan's take-out is very expensive, the cheapest cake costs 999 yuan, and the most expensive one is about 6 million yuan.

The reason why black swan take-out became popular is that it started with a short video on the Internet. In the video, a little brother is very handsome and has a high face value, and he is the takeaway of the black swan. Some time ago, it was also reported that the monthly salary of the black swan takeaway was over 11,111, but it is not clear whether it is true.
