28- 138 and 28-648 are both 28 series. I value 28-648 more. Although it is stewed treasure, it should be no different from 138. Its panel design looks very similar, but the words on it are different. One is porridge pot, and the other is stewed treasure. And why do you think 648 is more practical than 138? Because I think the time is my own. For example, if you cook porridge in Guangdong for four hours, you can set porridge on stew treasure for four hours. And 138 is 3.8L, which is too small to cook porridge, because it is best not to exceed 65% when cooking porridge, otherwise it will overflow the pot. The difference between these two paragraphs is that 138 belongs to southerners and 648 belongs to northerners.

It's best to go to a big shopping mall to see the real thing. In Guangdong, Gome has independent sales.
