Traditional Chinese characters of "ice"

The word "Bing" has not been simplified, although there is no complicated word, but there was a popular folk writing "Yi" (which is still used in Japan and South Korea at present), which can be used for reference. Then there is actually a word "Bing" that can be said to be formal, which is closer to the source of coinage, that is, when the prototype next to the word "Ying" is used as a radical, the word "Bo" is simplified to "Bo". Of course, the word "Bo" is completely equal to "Bing". Although it is not a complicated word, it can be called orthography.
