About 15 seconds.

In fact, the so-called "seven up, eight down" isn't a new way of shabu-shabuing tripe, it's just a way of saying that it takes seven seconds to fish it out and eight seconds to put it down, so it adds up to 15 seconds. So if you want to have a tender and crispy tripe, you can eat it after about 15 seconds of shabu-shabu, which will not be old, and will taste crispy, tender and fresh, which is very delicious.

Warm tips:

The most important thing to do when eating hot pot is to cook it well, so that it is safe and delicious. Duck sausage can be eaten in a few seconds, and slices of meat can be eaten just as they float up, which makes them tender, but in case they're not cooked, there's a risk of contamination by parasites or bacteria.

In fact, it's almost impossible to have a universal recipe for slicing meat with different thicknesses, different sizes of meatballs, and different cooking times.

To determine whether the food is cooked or not, the meat should wait until it is completely browned, not flow "blood" before eating. If you don't see any discoloration, you should wait a little longer to cook the meat until you feel comfortable that it's fully cooked.
