The landlord can drink a prebiotic meal replacement milkshake, which smells delicious. I feel full. It is a very practical meal replacement product.

Hello, when you say fan, you mean wind power generation equipment. It is no problem to install wind power generation equipment by yourself, but if you want to connect to the grid, you need to apply to the power company and pass their acceptance before you can connect to the grid. If you want to engage in wind power generation, you'd better apply first, and then install it according to their requirements after the power department agrees, otherwise it will be difficult to connect to the grid.
