Car-hailing company DiDi signed an agreement with TAL Education Group to provide free online courses for the children of taxi drivers. The courses, worth 30 million yuan, cover all subjects from primary to high school. Children can study courses at home, saving parents’ time to spend or pick up children from off-line after-school classes.

According to Zhu Jingshi, vice president of DiDi, all 153 million registered (注册) taxi drivers of DiDi can ask for the courses on the company’s mobile app. The car-hailing company will evaluate (评价) the drivers and provide courses on the basis of the time they became registered drivers with the company, the number of passengers served and evaluation from passengers.

The health and education of children have remained top priorities of Chinese parents, including taxi drivers. A survey done by DiDi and TAL showed that although the average monthly income (平均月收入) of taxi drivers is only 6000 yuan, many would like to pay 40 percent of their income for their children’s education.

The survey found that most taxi drivers were born in the 1970s and 1980s and worked seven days a week. More than 70 percent of them have children under 18 but very few have time to be with family and children. Only 8 percent of them said they had guided their children in doing homework. Because of these, 60 percent of drivers hope their children could receive the guidance from professional services.

Huawei, which rose rapidly to become the world's third largest smart phone maker, is aiming to make the gap(差距) smaller with leaders Apple Inc. and Samsung Electronics. But the company also faces challenges after losing its top spot in China, the world's biggest market, to new competitor Oppo last year.

In a company meeting, Huawei Group founder and CEO Ren Zhengfei asked all employees(员工) to work hard ."Or the company will fall apart," he said.

"Young strong men don't work hard, but just want to count money in bed. Is that possible?" Ren said. "Huawei will not pay those that don't work hard."

"Everybody is nervous, "said a 36-year-old engineer in the Group." We are now all thinking more of the next steps, realizing permanent employment(雇佣) with the company is no longer possible."

"In 2017, we will try to improve efficiency(效率) and profitability(利润) by focusing on organizations at all levels, every employee, and every detail, and strictly control costs and risks to make sure of the development, "Yu Chengdong said. "We can't stand low-performing managers who fail to make great improvements after working in a position for several years."

Huawei spent some money on international marketing events, getting footballer Lionel Messi and Hollywood stars Scarlett Johansson and Henry Cavill as spokesmen.

"We are not spending too much on marketing," Yu said. "Instead, we will spend more money on technology and innovation(创新), and services."
