Take note that
私房菜 is a terminology used exclusively by the mainland Tiongs. That's because when Chairman Mao was in charge, private kitchens didn't exist, they were shared, similar to army cookhouses. They are still consciously or subconsciously mentally and emotionally damaged from that, so they need to use
私房菜 to distance themselves from their disgusting past.
And he must be truly special to get a mention by CCTV.
