First of all, you can get more sunshine on the open balcony. As we know, China's economy is developing rapidly and effectively, so most people in society work in offices. People in the office are always facing the computer for a long time and can't get the sun. Sunlight has many good effects on all animals and plants, as well as on people. The balcony is not sealed, or most office workers want to get enough sunshine when they rest at home.
The second reason is to coordinate home decoration and plant flowers and plants. Now people's life is no longer food and clothing, but quality of life. In order to improve the quality of life and living environment, many people like to grow some plants at home. Plants need sunshine and some space, so the balcony is a good place. Imagine sitting at the coffee table on the balcony, sipping tea, enjoying the sunshine and enjoying the green plants in your eyes on the idle days at home. Very comfortable!
