Play with the food!
The smaller ones are called 八带（bā dài）； the one bigger one with the really long tentacles is a 马蛸（mǎ shāo）。(If you’re in China, you’ll need your VPN to see the video.)
When I was I kid, sharks, anglerfish, and octopuses were the coolest things in the ocean. This restaurant has everything but the sharks.
This isn’t the only place we play with live octopuses, but it is the most convenient. This night we were able to see them change colour and squirt ink at us. Homeschool points +1000!
