Great changes in Siyang
Siyang, a shining pearl(闪耀的明珠) in northern Jiangsu, China, has seen great changes over the years. Today, it is known as a National Garden County and is often called "the most beautiful county along the Grand Canal". Let's look at how it has changed.
In the past, the environment was poor. The streets were often narrow and dirty, and there was rubbish in many places. However, there were also large open spaces. Life was simpler. People lived in small, old houses. In their free time, they played cards or listened to the radio. For transportation, most people walked or rode bicycles.
Now, Siyang looks very different. The streets are wide and clean, with green belts on both sides. Many tall buildings have been built in those once-open spaces. People's lives have improved. Many people now live in new flats.
They can travel the world on the internet at home, and most of them have mobile phones. Transportation is more convenient. People take buses or taxis, and they can take a high-speed train to reach big cities quickly. Many families have their own cars.
These changes are not only about buildings and roads. Siyang is also famous as the "Hometown of Chinese Poplar Trees(中国意杨之乡)". It has many green areas, like the Olympic Ecological Park and Wulihu Wetland Park, making the city very beautiful. The population(人口) in Siyang has grown, with about 830,600 people now living there.
People in Siyang are enjoying a more comfortable life. The changes show how the county is developing while trying to keep its natural beauty.
