their hometown's development.
2. discuss and share ideas on what students can do to help
their hometown in the future.
Love My Hometown, Build My Hometown
With a deep love for their hometown, people of different ages and professions are contributing to its development and growing along with it. Today, let us explore three such stories.
The watermelon farmer
Liu Guanghui is an agricultural technology expert in watermelon farming. Although he is more than 70 years old, he still spends most of his days working in the sun on the farmland. He wears a wide hat, and his skin is brown from the sun. He loves farming
and has spent his life researching ways to improve it. On his days off, Guanghui provides local farmers with technical training and guidance for free. With joint efforts of the government, farmers, and experts like him, the farming economy in the province has
grown by more than one billion yuan over the years.
The flower live-streamer
Jiang Hui's friends and fellow villagers call her the “flower girl”. When she was young, Hui often visited her aunt's flower field after school, where she learnt how to grow flowers. She also showed great talent in putting different flowers together beautifully. After graduating from university, Hui decided to return to her hometown and start her own flower business.
To promote sales, she started to sell her flowers online. It was hard at first, but she didn't give up. She always patiently explained and offered practical advice to customers. Gradually,
her online shop became more popular. She also helped and taught other villagers how to sell agricultural products online. “Many people now know about the agricultural products from our town,” Hui said with a big smile. “This makes all the hard work worthwhile!”
The village teacher
When Yuan Bailing was a little girl, it took her almost an hour to get to school each day, but she loved school so much that she never missed it. As she grew up, she witnessed how her village
changed greatly over the years. Better roads and bridges have been built. Now it takes only ten minutes for children to get to school. As the first person from her village to graduate from
university, Bailing decided to return to her hometown to become a teacher.
She wants to help more children get a good education and be part ofher hometown's growth and development. Though the area still needs further development, through the courage and hard work of its people-like Bailing-it has a bright future ahead.
