# PRE-DOC: Roam

Have you ever imagined that? Life is a stand-alone game with hyper-internet.

Try to call the customer service number, after the beep, a lazy and firm male voice came from the noisy background: "Hello, the life you are inquiring about is not in the comfort zone, please try again later..." After hanging up unexpectedly, the body that woke up in the middle of the night, the patter of rain outside the window, and the church bells were all engulfed in this endless night.

At that time, on the northern land of the Alps, the horizon gradually became brighter.

The autumn beauty of Munich is so intoxicating. Fallen leaves of apricot, maple, and ochre cover the grass of the English garden. Under the Chinese Tower, there is a bustling crowd. On the table is the Bavarian-style crispy pork knuckle. And roast chicken, the golden wine brewed for Oktoberfest (Oktoberfest) is celebrated in hand, making the hustle and bustle at this moment very beautiful.

What could be more healing than the realm of the southern country, that is the autumn colors of the northern country.

### Beijing, Beijing.

At the age of sixteen, the first time I left the land of my hometown was excitement, hectic, confusion, or anxiety. In the pre-high-speed rail era when there was no EMU, the Z-head red-skinned train crossed the boundless North China Plain without sleepless night. As the train slowly entered the Beijing Railway Station, the broadcast began to broadcast the welcome speech from the capital, and I really felt that this northern country under my feet would be the habitat of my university for four years. When the scorching heat gradually receded, the ginkgo trees on the campus and in the West Diaoyutai Temple were glowing with bright golden colors overlapping the hills, and the maple leaves of the Fragrant Mountain and the Temple of Earth were dripping with red blooms. Against the blue sky, the clouds went straight into the sky. I was busy printing the autumn of this northern country.

When I am in Beijing, when I am confused, my favorite place to go is the square of Beijing North Railway Station. I can climb up to watch the flow of people going from north to south all night, my head can be completely empty, and there is an inexplicable sense of satisfaction and progress. strength. The person who is willing to accompany me to see is A. 

The prosperity of the prosperous city has lost the way for the people who drifted north. As Wang Feng sang in "Beijing" back then, when I walk in every street here, my heart never seems to be calm. What I can hear is the pulse and cruelty of this city, and the laughter and sigh of people. In Beijing, I left more than laughter and tears, but also more than confusion and hope. I remember when I first went to college, I heard a word, from then on, there is only winter and summer in my hometown, no spring and autumn. I didn't care about it back then, I felt too hypocritical, it was not just a train ticket to go home. After graduating from university, I went abroad to study, and I only returned to China in the summer. From then on, I lost three-quarters of my hometown in winter, spring, and autumn. Winter is approaching, and perhaps the wild goose heading north should have flown south.
