From a laid-off worker, through personal unremitting efforts, Hunan Huantong Technology Co., Ltd. was founded, mainly engaged in the production, installation and maintenance of mobile communication towers. The company has made great progress in the past ten years: the registered capital has increased from 500,000 to100,000. The company's annual production capacity is 50 million yuan, and the accumulated national tax is over 5 million yuan. Products radiate all over the province and are well received by all localities. In 2007, the company was rated as one of the top private enterprises in Changde 100. Since 2003, the company has been rated as "Contract-abiding and Credit-abiding Unit" by the administrative departments of provincial and municipal federations of industry and commerce. Since 2000, the accumulated tax payment has reached nearly 10 million yuan. He invented and designed "a mobile communication room" in 1999, "a hexagonal tower" in 2006, and "a self-supporting mobile antenna mast" in 2007, and successively obtained China National Intellectual Property Administration patents.
He is keen on giving back to society. Employees are regularly organized to travel, and the company has also set up a mutual aid foundation to help the poor workers in the factory. Liu Jianmao promised that if employees have two children to go to college, they can subsidize one of them. By the end of 2009, it had sponsored 13 employees' families.
At the beginning of last year, under his organization, the whole company was ready to go. The company quickly organized technicians to overhaul the mobile tower in the city, and there was no interruption of mobile communication caused by the collapse of the tower in the city. Liu Jianmao took the initiative to ask the provincial mobile company to participate in the anti-ice rescue in the province, and set up his own anti-ice rescue team as the chief commander to participate in the anti-ice rescue work in Chenzhou. He and his employees have been busy from the 26th of the twelfth lunar month to the first month, and the donation project for disaster relief is worth 400,000 yuan. On February 12, 2008, CCTV reported the company's participation in Chenzhou's anti-ice disaster relief work in the news broadcast program. During this period, Liu Jianmao himself received a message of condolence from Comrade Wang Jianzhou, President of China Mobile Company.
After the Wenchuan earthquake in Sichuan last May, the company sent more than 20 people to Guangyuan, Sichuan four times with its own designed iron tower. In May this year, Liu Jianmao once again organized employees to install three 20-meter-high six-party communication towers produced by the company in Banqiao, Qingchuan County, Jiujiaya Village, da yuan xiang and Minzhu Village, Ma Qi Township. The donated three communication towers are worth 400,000 yuan. Up to now, he has led Huantong Company to donate nearly 1 10,000 yuan to disaster areas and vulnerable groups, and donated more than 200,000 yuan to new rural construction. Many media such as Changde Daily and Changde Evening News spoke highly of his and his company's helping behavior.
