This topic reminds me of a saying by a famous Chinese writer that goes, "The weather in spring is like a child's face, changing irregularly, smiling now but crying in the next moment." Yesterday, the temperature here rose up to 20°C, giving me the feeling that tomorrow would be summer. However, as you may have guessed, it is cloudy today and I felt chilly on my way to work. The temperature changes like a rollercoaster ride, turning my happy mood into a sad feeling in just one second as I stepped out of my apartment. In fact, I have already gotten used to the weather in spring, but I always hope to enjoy warm spring days out of the blue after experiencing a long, tedious winter that kept us indoors and made us long to be close to nature. After all, the blooming flowers and green world usually represent hope and new beginnings.
