In reference to the patent: WO2016169199A1
This patent application clearly copies prior art US6464275 October 2002 and other prior art that is clearly improved upon by US7721837 May 2010.
It is believed that CN/China Nation is used within their country where by their own law in 2001 they can not challenge any prior art and they use WO/World Order to file for patents in other countries, can anyone elaborate?
