I write straight into the paper log book too. I hold the key though, not just rest my fingers on top. After taking those code groups, eg 3D6A U4D6 AAN7 (or 3861 2486 1197) etc, I suppose they look up the words or characters in a book. Is this system used by Chinese amateurs?

Yes well not by amateurs perhaps, I have yet to hear two Chinese radio amateurs using Chinese (4 digits) CW. I always hear them having QSO using English abbreviations no doubt knowing the Chinese equivalent, e.g. TKS OM FER FB QSO HPE CUAGN is what they use, it is nice to hear the old style "rubber stamp" QSO among Chinese hams, sadly abandoned and forgotten by many native English speakers, which is actually a great disrespect to non-English speakers who learn ALL the abbreviations and their corresponding meanings in their own languages! How easy do WE have it and yet we constantly hear complaints from new telegraphists that there are too many abbreviations to learn. But for commercial e.g. Chinese ships, that's what they do, and I guess they get to know many, even thousands of number groups by heart after a while. The military encode these into other numbers, and this would be very, very easy to do, using modulus mathematics when added or subtracted from a random (unbreakable) key or a non-random, e.g. autokey or fixed key.

There is a very good explanation of this conversion of Chinese to CW and the Code Books used here:

If Chinese CW is anything like Chinese cardboard, I don't want to go there.
