China Hefei - "New Diapers"??

As you can see, I was equally surprised to see this new feature in the diapers....
I gave a thought that this might be some new design for toddlers... give it a shot!

So, after coming back from where I was working, I happened to stop by in a grocery shop near my place, this 1 year old toddler of the owner happened to smiling, and teasing with me.....

Then, as soon as he was trying to be playful yet started to cry because of stranger (in this case, happened to be me!), he was lifted by the mother and I was seeing something that I have been seeing in the earlier day......

So, do you have any idea what's that for???

Finally I asked the owner and she gave me the answer.... which I am going to share with you. However, before that I must tell you that Chinese People nowadays are getting very environmentally friendly with their lifestyle, because they are aware of the global issues...
e.g. I am paid for the plastic carry bags in Supermarket.

Anyway, back to the diaper thingy, as far as the environmental-friendly mindset is concerned, the design of this diaper which there is an opening right in the ass is for "producing" poo & nothing else!

Simple to "process" & easy to "clean" isn't it... no Pampers, no Huggies... interesting...:)
