What do you sell at the gate of the power plant to make money at low cost?

Setting up a stall to sell food and beverage snacks should be a common project at the entrance of many factories, but it is also a project with good sales. Workers usually choose to buy something to treat their stomachs after work. Dining snacks can be made into breakfast, lunch and milk tea drinks. The cost is not too high, but they also have unique competitive advantages, such as taste, hygiene and characteristics. 2. Set up stalls to sell vegetables and fruits. Vegetables and fruits are generally sold in the vegetable market, but the vegetable market is generally not near the factory, or it may be far away. Workers are very tired after work and have no energy or time to buy these things. Therefore, we can sell fresh vegetables and fruits at the factory gate, so that workers can take what they need home easily.
