What you want to take from India is something you will have to decide and you will have to spend some time researching this (if you are sincere and not trolling). I don't think we can help you much here since we don't know your context and where you are coming from. From one perspective you can pick up a lot of things from India and another nothing. It all depends on what you are looking for.
If I have to pick one thing from India then I will pick
Right to Information ACT. I don't know if you have something like this in China but I have really seen how this act has empowered common people in India.
Also there are certain Constitutional Bodies in India e.g. CAG, UGC, Judiciary etc. are interesting case study. They are the Insitutions that keeps checks and balances on the government and are Independent. Yeah CAG is how we know how corrupt our govt is. Not sure if you have something like this in China. Since corruption about China only comes out in NYT. So eithe you don't have corruption or you don't have any checks and balance. Your pick.
Hope this helps.
