In 1989, Sanmao, a famous Taiwanese female writer, came to Shanghai to find him, and he hailed her as a literary genius. In his later years, Zhang Leping devoted great enthusiasm to the cultural exchanges between the two sides of the Taiwan Straits. In 1991, he won the special prize for his "People's Cross-Strait Love" essay by the Central People's Broadcasting Station. On April 4, 1991, his last comic book, "Cat Feeding Rats", was published in the Liberation Daily. In the winter of the same year, Zhang decided to donate the manuscript of San Mao to the Shanghai Art Museum.
