The Keep Running team and guests Justin and Yang Di came to Wenzhou. The program team set up a "mystery mission". The sandbags with the number of catties written in everyone’s backpack are the items they are trying to get rid of. At the same time, they have to test the weight of Cai Xukun’s “idol burden". If you win in each round of the game, you can enjoy the chef’s dinner. If not, Cai Xukun would have to make the food.
