The green alley is only narrow enough to accommodate the two of us side by side; next to the street, there is a hot steamed bun shop, and I will pass by it every morning. And... That, long time no see you. The young alley has been renovated countless times, and the old man of the bun shop has opened a bun shop with a front. What should be there is still there, but will you still wait for me where you are? Or already "human beings have changed".
