That's certainly good news. I'd read somewhere that he was in his 80s, and this was probably a couple of years ago. I hope having a project such as this to work on is contributing to his health and longevity.
Unfortunately, even though the earlier volumes are coming out in paperback, they are still at least $30 each. That's well out of my reach.
On the subject of giant Chinese novels, I am plugging away at A Dream of Red Mansions (aka The Story of the Stone) by Cao Xueqin. I'm reading the 5-volume Penguin edition of the version that was completed by Gao E. Have any of you read this work? I'll report on it in full when I finish, which should be in a few weeks at most.
