China-Africa Salon: A stadium in 2 years, a bond of 42 -- Chinese builders share their Kenya story_我的网站

"The schedule was extremely tight -- just two years, while comparable projects elsewhere usually take more than three," Du Xiao, project manager of the stadium for China Road and Bridge Corporation (CRBC), told Xinhua in a recent interview. "There is a very real sense of pride."
According to Du, the stadium has no running track, bringing spectators close to the pitch. Its seats take on the green, red and black of Kenya's national flag, while the facade features the traditional shield and spear of the Maasai people.
Upon completion, the stadium is set to be renamed the Raila Odinga International Stadium, in honor of Kenya's late former Prime Minister Raila Odinga.
The roof adopts a cable-supported grid system erected with a "cable-first, steel-after" method, which Du said is the first of its kind independently designed and built by China. Without temporary steel supports, 48 radial cables are tensioned to lift six ring cables before steel trusses are laid on top, saving at least three months of construction time, with displacement controlled to the millimeter. In 2025 alone, some 1,300 containers of materials and equipment were shipped from China to the site.
For CRBC, the stadium is only the latest chapter of a much longer story. The company built its first road in Kenya in 1984, and over 42 years, its footprint has extended from roads to bridges, ports, railways and buildings.
Du Shan, the executive general manager of CRBC Kenya office, recalled that before 2008, Nairobi was cut apart by three rivers and a cross-district trip could take more than three hours. After CRBC completed the ring roads, the journey now takes about 50 minutes. The company is also expanding the A8, a national trunk road, from two lanes to four and six, she said.
On the Mombasa-Nairobi Standard Gauge Railway, wildlife corridors were built with a clearance of more than six meters, "so that giraffes can pass with their heads held high," Du Shan said.
"Working overseas, we should not arrive thinking about changing the place. We should first adapt to and learn from the local community," he said. "What many projects truly open up is not just roads and railways, but trust between people."
The stadium sits near Kibera, Kenya's largest informal settlement. Du Xiao remembers a local young man named Sammy, who had no skills when he applied for a job but volunteered for the project's equipment training and became a pump truck operator. "I asked him why he worked so hard. He said, 'I never thought I would have the chance to touch these machines. Now I feel I can support my whole family.'"
According to Du Shan, the project recruited nearly 500 young workers from the neighborhood during construction, many of whom have qualified as assistant engineers, while about 280 local youths were mentored into technical backbones during the construction of the Mombasa-Nairobi railway.
More than 350 CRBC employees have worked overseas for over a decade, and each year the company awards them a gold medal for long-term dedication, she said. "The medal is not only an honor, but also a kind of warmth. Because 42 years -- it has truly not been easy."
When his child was born, Du Xiao was at a critical stage of the Nairobi Expressway project and could not make it home. "People in overseas engineering live in two worlds -- the project site on one side, the family on the other. All you can do is try to do a little better on each side," he said.
"Maybe I will one day leave this country. But this stadium will remain," he said. "I came here to build projects. Then I found that this country has shaped who I am today."
。所有约8000名参与者都被问到：你在一个普通的工作日晚上有多少个小时的睡眠时间？"一些人还戴上了腕上的睡眠追踪器。在20年的跟踪调查中，他们被检查出患有慢性疾病，包括糖尿病、癌症和心脏病。那些在50岁左右睡了5个小时或更少的人比那些睡了7个小时的人患多种疾病的风险大30%。50岁时睡眠时间较短也与研究期间较高的死亡风险有关，主要与慢性病的风险增加有关。来自伦敦大学学院和巴黎城市大学的研究人员说，专家们一般建议睡7或8小时左右。
