Southern Song scholar known for 履斋示儿编, a book of notes on the classics, poetry, and the writing and sounds of characters, compiled to teach his sons and still used as a source on Song scholarship.
The 示儿 in his title, 'to instruct my sons', also names 陆游's deathbed poem 《示儿》, which asks his sons to tell him at the family altar when the lost north is won back.

奕 is a favourite in modern given names, as with the singer 陈奕迅 (Eason Chan). Don't confuse it with 弈, the board game Go, as in 对弈 'to play a game of chess or Go'.
