James, for what it's worth - and this may sound over-simplistic, but I find the best way to get more earth Chi is literally to practise on a natural surface such as grass. Recently, I've abandoned the garden where I used to practise in the park, as too many members of the public go in and disturb my concentration. So I've taken to practising on vacant tennis courts instead and curiously enough, I'm finding it much more difficult to keep my root on the tennis courts, even though they are much more even than the grass surface. For instance, I have more difficulty balancing on one leg for slow kicks on asphalt than on grass; that is to say, I have to concentrate harder to keep my balance, which was easy on grass. I think that this may be due to a lack of earth Chi getting through from the ground on an artificial surface. Kind regards, T.
