Around 223, when the states of Shu Han and Eastern Wu reestablished their alliance against their rival state Cao Wei, Zhuge Liang, who had become Imperial Chancellor of Shu, sent Deng Zhi as an envoy to Wu to meet its ruler, Sun Quan. One of Deng Zhi's tasks was to seek the release of Zhang Yi and bring him back to Shu. Only then did Sun Quan meet Zhang Yi for the first time. During the farewell banquet he held before sending Deng Zhi off, Sun Quan spoke to Zhang Yi and was very impressed with him. Later, after Zhang Yi left with Deng Zhi, Sun Quan regretted letting Zhang Yi leave because he wanted to recruit Zhang Yi to serve under him. He then sent his men to pursue them and bring Zhang Yi back, but Zhang Yi already sensed that Sun Quan did not want to let him leave, had sped up his journey upon leaving Wu and returned to Shu just one day ahead of Sun Quan's men.
