冫 is also the 18th indexing component in the Table of Indexing Chinese Character Components predominantly adopted by Simplified Chinese dictionaries published in mainland China.

• Bronze script character
• Large seal script character

Note that in modern Traditional Chinese, Simplified Chinese and Japanese, radical ice in some characters (e.g. 冬, 寒) is now written as two dots. Their original forms are retained in Korean hanja and some old Traditional Chinese typefaces (e.g. 冬, 寒).

In both Unihan database and mainland China's standard,^[2] the Simplified Chinese character 习 (=習) falls under radical second (Unihan: 乙部, China: 乛部 or its variant form 𠃌) instead of radical ice.
