A Cuban girl reads the book "100 questions about China" written by Rolando Lopez, a political counselor of Cuba's embassy in China in 1974-1978 and ambassador in Beijing in the 1980s, at the Confucius Institute of the University of Havana in Havana, Cuba, March 20, 2019. "I felt that obligation because of the historical links with China," Rolando Lopez said, and for that reason he wrote a book "100 questions about China" to encourage Cuban readers to learn more about the Asian country, including its peculiarities, history and traditions.
