What are the shortcomings of Mudanjiang's current green space system layout?

The biggest disadvantage is that there are no trees in the commercial street in the city center, especially the pedestrian street. In summer, there is no place to bask in the sun. In the past, there were many old trees on the pedestrian street, surrounded by wooden chairs, so it was comfortable to sit in the shade and rest. Now I really don't know who planned the pedestrian street.
