"When God closes a door in front of you, he will open a window for you" tells us that God never closes a door, but he will open another door. When encountering difficulties and setbacks, looking at the problem from another angle will lead to another world. There is no way to go because of the winding water flow in the mountains, and a mountain village suddenly appears in the willow-green flower bay. As long as you have a positive and optimistic attitude, the solution is always more difficult than it is. Struggle with confidence and don't give up, we will certainly open up a new road and move on.
