I happen to have a rice cooker in the sky,1l. Usually stew soup before going to bed at night and turn on the automatic gear. After stewing, it will automatically jump to the heat preservation file. Because the power is small, it takes about 5 or 6 hours to open the automatic transmission. If you want to stew it quickly, stew it for 2.5 to 3 hours. Two days ago, I stewed the melon sparerib soup for more than 2 hours, but I felt it was not long enough. Try to stew for a while if you have time. You can also practice stewing at home, and if you use it more, you will master the heat.
