'China helped us when help was most needed' — The Tanzania-Zambia Railway: A testament to China-Africa friendship chinadaily.com.cn | Updated: 2021-06-22 16:01 Share CLOSE It was the beginning of the year 1970. News came that Wang Xingguo was about to work on a railway project in Africa. His wife Zhang Yunhua was very reluctant to let him go: Africa is so far away and their sons are still too little — the elder one is three years old and the younger one is only two. Wang tried to explain: He is a cadre, a CPC member; when duty calls, he must be the first to sign up. In October that year, Wang, together with over 1,000 co-workers, got on board the ocean liner Jianhua in Guangzhou and left for Tanzania.
