Family devoted to Africa's success helped lay tracks for its development

Separated by generations, two men shared a vision that benefited many

Almost half a century ago, Li Yongzeng ("Li Snr"), now 80, was among tens of thousands of Chinese people who were working in Tanzania helping to build the 1,860-kilometer Tanzam Railway, or TAZARA, linking landlocked Zambia to the Tanzanian port of Dar es Salaam.

Now, his 25-year-old grandson Li Shangyi ("Li Jnr") works in Malawi on the program of "Access to Satellite TV for 10,000 African Villages", part of China's aid to Africa to build the information highway as announced by President Xi Jinping at the Forum on China-Africa Cooperation Johannesburg Summit in 2015.
