Why? The tags are used interchangeably. Not just in China, either. Even with Japanese products NTR is used interchangeably for both. It's almost like the abbreviation for both Netori and Netorare is NTR.
I don't know where this narrative that NTR only means Netorare came from.
It's like PWP - it may be stupid as hell but it can mean either Porn Without Plot or Plot With Porn; and is used interchangeably for both.
