Write a 450-word travel composition on National Day Yulin Garden Expo Park.

Today is the fourth day of National Day. Although it is raining in Mao Mao, it can't extinguish my happiness of going to Chengdu to study at my sister's university. The car was full of songs and words, and everything was immersed in the festive atmosphere of National Day.

Early in the morning, we arrived at my sister's school, Sichuan Normal University, unconsciously by car. As soon as I got off the bus, I saw the tall and majestic teaching building, and the banner of "Celebrating National Day" hung opposite the school gate. I thought I came to the park. The campus environment was elegant and the scenery was charming. The flowers and trees in the garden give off bursts of fragrance. Flowers are blooming around, as if welcoming guests from afar. There are celebrity heads on both sides of the aisle on campus! Confucius, Li Siguang, Beethoven, Nobel and others. There are spacious sports grounds, beautiful classrooms, magnificent office buildings and so on. The campus is full of cultural atmosphere.

After lunch, my sister and I went to the bustling downtown, and the endless traffic came and went, which was very lively. We came to the long-awaited "Pacific Department Store", which contains beautiful clothes, my favorite toys and dazzling items.

It was getting dark, and when we parted, my sister shed tears. At this time, I said to my sister with deep feelings: "Sister, you should add more oil, learn skills and contribute to the prosperity of the motherland." On the way of waving away, I also secretly made up my mind: I also want to study hard and make progress every day like my sister.

This car runs as fast as lightning. On this day of National Day holiday, I am really happy. I wish our motherland a better and more prosperous future. Ah! Today is my happiest day and my most unforgettable day!
