Counting (计数)

I've been reading up a bit about counting and counting related subjects in Chinese. Attached here is a nice summary of what I've been learning. Counting in Chinese is actually quite simple. It only becomes a bit more tricky at about 100 000 (十万) but even then its quite logical. I have found that reading and writing Chinese numbers are much easier than speaking them out loud. It might just be that I am more analytically and visually focused. On my long run this morning I started counting in Chinese in my mind from 1 (一) to 100 (百）and then in increments of 100 from 100 (一百) to 900 (九百). This is quite a nice exercise to do while running or in the gym.
