She is not alone. Many cases of students in remote areas trying everything possible to get an internet connection for online classes have been mentioned on social media.

A 21-year-old girl in the Tibet autonomous region walked two hours each day to climb a mountain where she could get a network signal and take online classes taught by her school in Hunan province, Xinhua Daily Telegraph reported.

Guo Cuizhu, a middle school student from Liufen village, Henan province, is known as a popular "freeloader" for using the village committee's Wi-Fi.

"Her family is poor, which is why they don't buy broadband service and her father's phone doesn't have enough mobile data for her to take online classes," Zhao Yaomin, a public servant working at the village, was quoted as saying by Luoyang Evening News.

Fortunately, such difficulties are being gradually solved by governments, schools and related companies. Communication base stations have been established in many mountainous areas. Further, some poor families have been provided with free broadband services and equipment, while others have phones that have been supplied with free data packages.

The country also has projects underway to equip remote areas with smooth network services.

For example, China Mobile is setting up more than 2,000 base stations for 4G signals in the Guangxi Zhuang autonomous region's rural and remote areas with an investment of 400 million yuan, according to China National Radio. The project was started in September and is expected to be completed by May.
