In the town of Lagado in the northern region of Cameroon, located over 900 kilometers from the capital city of Yaound é, the vast Benue River is intercepted by a towering dam, creating Lagado Lake with an area of over 500 square kilometers. Beside the dam, a monument towering over ten meters high stands tall. The craftsmanship spirit of the Chinese people is admirable, "said Ahmadu Beong, the production general manager of Eneo Company, which is responsible for the management of Cameroon's national power grid, as he looked at the monument with respect in his eyes. On the top of the monument, the flags of China and Kazakhstan appear particularly bright under the scorching sun. On this monument where China assisted in the construction of the Lagado Hydroelectric Power Station in Cameroon, two sets of numbers, "1978" and "1984," are engraved silently, telling the story of the tumultuous years of the station's construction and completion. During a visit to the factory, Bi Weng sighed and told reporters that the completion of the Lagado hydropower station has greatly helped the development of local agriculture, fisheries, and tourism industries. More importantly, to this day, the hydropower station is still the core power source for the three regions of Adamawa, the North, and the Far North in Cameroon. Tangible monuments stand on the river, while intangible cultural exchange imprints blend into daily life. During a visit to Lagado town, the reporter unexpectedly heard that there are three tofu shops in the area. In one of the simple and crude workshops, young Buhari Ahmed is skillfully directing the employees to filter the bean dregs and squeeze soybean milk. He jokingly referred to himself as the "second generation of tofu". "I heard from my father that many Chinese people came to build the power station back then, and they loved to eat tofu. They taught my father step by step. Now, tofu has become a specialty food in our Lagado." What moved the reporter even more was the Chinese sentiment deeply ingrained in the hearts of the older generation in the local area. After multiple inquiries, the reporter found Umaru Bakari, a local elderly person who had participated in the construction of the hydropower station. As soon as he arrived at the entrance of the hospital, the elderly man with gray hair greeted him and said in a slightly Yunnan accented Chinese language, "Come in! Welcome!" This surprised and moved the reporter. Entering the courtyard, Bakari's two granddaughters also greeted him in Chinese, saying "Hello!" In the simple living room, the old man took out a stack of yellowed photos and pointed to the characters above, telling his stories with Chinese builders one by one. In 1974, at the age of only 17, Bakari came from Galua, the capital of the Northern Region, 80 kilometers away, to Lagado to conduct geological exploration with a Chinese exploration team. In the following 10 years, he followed the Chinese team to experience the entire process of hydropower station construction and operation. At that time, there were about 800 Chinese and 2500 Cameroonians working together. ”Bakari recalled. At that time, Lagado was just a small village covered in swamps, without many large machinery and equipment. Workers from China and Kazakhstan relied on their shoulders and worked day and night to build this hydropower station. I still remember Hong Gong, who called me 'Little Umaru' and taught me a lot of skills, which allowed me to stay and work at the hydropower station. ”However, since the Chinese builders completed and left in 1984, Bakari has lost contact with them. I miss them very much. ”The old man wiped away the tears from his eyes and whispered, "Now there are new Chinese people in the town, maybe I can continue to speak a little more Chinese." The "new Chinese people" among the old people are the China Electric Power Construction team who are continuing to struggle by Lake Lagado. During the May Day holiday, reporters visited the site of the irrigation project on the left bank of the Benue River. In the scorching weather of over 40 degrees Celsius, workers in China and Kazakhstan are rushing to seize the last "golden construction period" before the rainy season in June. Project manager Hu Jinzhong told reporters that the project will directly draw water from Lake Lagado and is a comprehensive agricultural water conservancy project that integrates functions such as water intake, water transmission, drainage, and flood control. After completion, the pipeline irrigation system will supply water to nearly 3000 hectares of land in the area. This can also be considered as' planting trees by predecessors and enjoying the cool breeze by later generations'. ”Looking at the shimmering lake in the distance, Hu Jinzhong said, "It is precisely because of the hydroelectric dam built by our predecessors that Lagado Lake and the water source foundation for our current irrigation project have been established." Remembering the source of water and never forgetting our original intention. At the end of the visit, Hu Jinzhong took the reporter to a special quiet place - where four Chinese builders who sacrificed their lives in the construction of a hydropower station more than 40 years ago lie in eternal peace. Under the scorching sun, the tombstone appears desolate and majestic, worthy of admiration. We hope to inherit the spirit of our predecessors in foreign aid projects, build new high-quality projects, and make the local people recognize today's new generation of Chinese builders just as they recognize the Lagado hydropower station. ”Hu Jinzhong said.
