When the warlord Liu Bei was stationed at Xinye County, Xu Shu visited him and received a warm reception. Xu Shu recommended Zhuge Liang as an adviser to Liu Bei and told him that he must visit Zhuge Liang in person (i.e., he cannot invite Zhuge Liang to visit him). Zhuge Liang later came to serve Liu Bei after the latter visited him thrice and consulted him on the affairs of their time.
