Meat: Beef and mutton are self-evident and essential. It's best to put some ribs at the bottom of the pot, so that the stewed soup will be particularly fragrant.
Finished meat products: lunch meat, duck breast meat, ham balls (seafood balls, chicken balls, pissing fish balls, wrapped fish balls, sweet or not, basically everything cooked in Guandong can be bought from the supermarket).
Seafood: It is not recommended to eat fish because it has thorns. Once boiled, other dishes in the pot will be covered with fishbones, which is very troublesome to eat. If you really want to eat fish, buy some fish with only thorns, such as cod. Shrimp, scallops, squid rolls (ready-made in the supermarket), crabs and kelp (this is also found in seafood, and it tastes good when rinsed out).
Bean products: tofu vegetarian chicken (I don't know if you have it there, it's cylindrical, it tastes very strong and delicious, and it feels like meat when rinsed out).
Eggs: Eggs can be fried and put in quail eggs (peeled and put in after cooking).
Rice: Rapi rice noodles, instant noodles, jiaozi, noodles.
That's basically all here, and there may be something I forgot to write. The most important thing about shabu-shabu is that the soup base is delicious and everything is delicious.
