As of that time, I didn't realize there was anything can induce my (emotions) about this scenery, nor did I expect that the first time I returned to this nostalgic city (was as a tourist), walking out of the south gate of Beijing railway station, and turning around, I suddenly saw the Ming City Wall standing up resolutely under the setting sun in April and hided by the tender willows.Something had withered in my heart suddenly revived. Even today, after more than ten times of spring by autumn, the scenery that I didn't care about at that time emerges absolutely in my mind. The fragrance of the undulating grass, the uneven city walls, the sparkle of the moat, the winding white clouds lingering in the blue sky, and the shy peach and apricot blossoms with sparks, but more of them are those beautiful images that are still unknown with faint fragrance. To be frank, at the age of seventeen, all I thought about was myself, a beautiful girl walking next to me and a few inches of March spring grass between us. The gentle breeze blowing through the grass slightly brushed her beautiful hair, and immediately blew towards the distant forest, with magpies wandering among the trees like several white plum in the bush. Later on, there were still many tourists, but they couldn't slow down the frizing of the atmosphere between us. Although destiny always gave people an indication before putting to death, it was even more cruel when it came to doing it. What had brought me a hazy sense of melancholy is that that was probably the last time I see her face. In the following year, it's time for dask,and the air gradually thinned out, not only giving a sense of suffocation but also indicating that a brief night---- different from the previous eighteen years---- was about to set. When the rising sun rose again, I didn't know what kind of sky would cover what kind of land.The time it takes to visualize her face in my mind grew longer and longer as the day passed, and it extended so rapidly that it was like the shadow under the sunset and quickly melted into the dark night. I only remember her eyebrows slightly curved,when she laughed sometimes.Her eyes always fixed on you, and the nevus around her eyes like stars nestling against the sunset, while talking about the things beyond in college. Even years passing by, I couldn't help but feel a kind of shock, which continues to this day, no longer related to the beauty of her appearance. When I suddenly realized what it was, it was about four years later, during the winter vacation. Unexpected, Beijing experienced a heavy snowfall that had not been seen in many years. I came out of the research institute where I was interning, walked through a dark corridor, and fell into purity. At that time, I was doing all sorts of boring chores, and I knew it was just piling up time. In fact, my mother know more about the cruel aspect of it.During that time, she gradually developed the habit of closing the door after leave my room, and my grandfather, who had been looking forward to that someone in my family can gain both fame and wealth for a lifetime, also slowly gived up under the continue disappointment. Watching the day after day, the Mountain in distant west suddenly immerse itself into a bright twilight, and after snow the early winter sun shrouded in the wandering clouds,which was about to draft away. It was only then that I realized that what she had awakened in my second year of high school was actually a part of myself, a longing and wandering that was as innocent and romantic as burning, A Roman Holiday style betrayal and confusion towards banality life. I was gently woken up by my wife. It was evening. I settled them down. It seemed that I was induced by something to go there. The city wall was cut short, and the moat was also covered. The tourists at night did not decrease, but their feet were all sticky. I walked quietly, as if I were lying in a long stream, watching the gurgling water, the sparkling light, the old streets of this city, the stars beside the sunset, beautiful hair, smiling faces, falling flowers, broken bricks, and snow fields, Empty beer bottles and train train tickets from Beijing all slowly drifted by. And this is mostly like fleeting time, with floating memories and hidden emotions swaying under the moonlight. Even if we lose the complete pictures of the past, it is indeed the whole of our lives. Except for death, it cannot be erased, and anything else is just a moment of sadness or joyness, which will slowly sink into it. The night was deep, and the waning moon gently brushed over the edge of youth. The broken wall slowly extended towards ending of life, not far away.I couldn't touch anything from that stream except myself.
