What do you mean by correcting, adding or deleting Bu Yi?

Add and subtract divination is a book of divination application. Bu Yi, a divination application based on Na Jia method, also collects Liu Bowen's golden strategy, which is a required reading for divination application. On the day when the divinatory words in Jia Jian Oracle Inscriptions were corrected, he asked his father Wang's coffin to accept the "gift" sent to him.
