Mr. Yu had been taught by his father to always be an honest, grateful and open-minded person. He bears well in mind his father’s inculcation. As a catalyst for social development, he never forgets to repay the society while his business became gradually large.

In 2011, as proposed by Mr. Yu, BLD established Baolide Aid Fund and Baolide Child Care Fund in partnership with Hangzhou Charity Federation and the Children’s Hospital of Zhejiang University School of Medicine. The funds were set up to financially support children suffering from serious illnesses, and they make donations to over 20 seriously ill children every year after their establishment.

In 2018, BLD made a donation to Zhejiang Entrepreneur CSR Samaritan Fund. Charity programs, like support to college entrance examination, one-to-one poverty alleviation in a village of ethnic minority in Lishui, the Winter Warming event in Sichuan Province and Baolide Library in Guizhou Province, are also philanthropic endeavors made by BLD people with strong sense of social responsibility.

In 2019, BLD, along with Sina Sichuan, donated new tailor-made thermal sweatshirts with fleece lining to 119 kids in Yida Village Primary School and Zaganluo Village Primary School in Wagu Township, Meigu County, Liangshan Yi Autonomous Prefecture, Sichuan Province.

In 2020，Mr. Yu, in the name of BLD, donated RMB 1,000,000 to Charity Federation of Xihu District to fight against COVID-19 pandemic. The donation was intended to be used by medical institutions in Zhejiang to purchase personal protective equipment including protective clothes, goggles and KN95 medical masks. In addition, he donated 10,000 KN95 masks and 10,000 medical masks sourced from various channels.

In July 2021, Zhejiang Province was hit by Typhoon In-Fa and some areas in the province suffered from a big flood. Mr. Yu was very worried about the affected areas. After urgent preparation and arrangement, BLD, in partnership with Zhejiang Sanlian Rescue, formed a rescue team to deliver relief supplies to affected areas and assist the militia rescue team in searching and rescue operation. In the same month, Songjiang was hit by the long rainy season, and the grapes in the vineyards rotted away because farmers had no time for harvesting them. BLD, in active response to the government's call, organized customers to go to these vineyards for picking grapes, which relieved the farmers of their pressure.

In August, 2021, Shengzhou, Zhejiang Province was hit by a sudden rainstorm, and the accumulated rainfall in Guimen Township reached 114.2 mm. Due to the rainstorm, the township was flooded and the villagers’ houses were destroyed. Under the leadership of Mr. Yu, BLD organized a public welfare activity with the theme of “Love is Around You” to delivery disaster relief supplies to villagers of Guimen Township. In the same month, when it was hot summer, BLD, in cooperation with Jiaxing Traffic Broadcasting, organized a Mercedes-Benz convoy to the urban areas of Jiaxing to delivery heat relief supplies to people working under the summer sun.

In December, 2021, led by officials from Louxing District Administration for Market Regulation of Loudi, representatives from BLD made monetary donations and sent daily supplies in person to over 40 families in Zimu Village, Shexingshan Township. In the same month, Shaoxing, Zhejiang Province suffered repeated and severe COVID epidemic. BLD delivered more than 1,000 epidemic prevention supplies and mineral water to Zhuji fire brigade, traffic police brigade and communities to send its greetings to people working in the front line of epidemic prevention and control.

In March 2022, there are national epidemic outbreaks in many regions, with confirmed cases of new coronary pneumonia and asymptomatic infected people found in Shanghai, Jiaxing, Loudi, Haining and other places. Under the call of Mr. Yu, BLD volunteers have brought materials to the front line and help carry out community nucleic acid testing, distribution and transportation of materials, verification the data of epidemic prevention and control, and education of residents on prevention and control policies and other support work, helping to fight the epidemic through practical actions. As Mr. Yu is concerned about the outdoor operators working under high temperature in the hot summer, BLD launched cool summer themed welfare activities in Shanghai and Shaoxing in August to give away summer supplies and show sincere care to the front-line sanitation workers and construction workers.

In response to the call for supporting agriculture and rural revitalization, as well as helping to protect and reforest Xinjiang and protect the environment, in 2023, under the advocacy of Mr. Yu, BLD participated in the large-scale public welfare action of "I Have a Tree, Growing in Aksu" jointly sponsored by a number of organizations, and joined hands with BLD's users in planting trees in the cloud to help promote green development.

Mr. Yu also cares about the growth and life of every employee. With support from Mr. Yu, Business School of BLD was established to support development of young employees by means of one-to-one mentoring. BLD also set up Baolide Employee Care Fund, to grant allowance to employees or their family members suffering from poverty or disability due to illness. At the end of each year, representatives from Baolide Labor Union Committee and Employee Care Committee would pay home visits to employees in difficulty.
