attendants and personal staff. As crown prince As Sun He was intelligent, Sun Quan favoured him and often kept him by his side. Sun Quan also treated Sun He exceptionally well; he gave Sun He new clothes, ornaments, toys and other gifts, but did not do the same for his other sons. Sun Quan's subjects also highly regarded Sun He because he was not only bright, perceptive and well-versed in literary arts, horse-riding and archery, but also respectful and courteous towards his tutors and elders. He was genuinely interested in getting to know people. In 247, Sun Quan ordered Zhuge Yi () to pretend to defect to Wu's rival state, Wei, and lure the Wei general Zhuge Dan into a trap.

As he saw that weiqi was an unproductive activity meant to be a hobby or pastime, he became worried that Cai Ying and the others would become complacent and neglect their duties from playing too much weiqi. He thus came up with an idea to subtly
