YES stroke alphabetical order

The YES stroke alphabetical order (Chinese: 一二三漢字筆順排檢法), also called YES stroke-order sorting, briefly YES order or YES sorting, is a Chinese character sorting method based on a stroke alphabet and stroke orders. It is a simplified stroke-based sorting method free of stroke counting and grouping.

"YES" in the English name is the acronym of Yī Èr Sān, the pinyin expression of the Chinese name. The Chinese name Yī Èr Sān (一二三; lit.'one, two, three') is in turn formed by the first three of all the Chinese characters in YES order (because stroke "一" lies at the top of the alphabet).

YES order has been applied to the indexing of Xinhua Character Dictionary and Xiandai Hanyu Word Dictionary. In this joint index the user can look up a Chinese character alphabetically to find its pinyin and Unicode, in addition to the page numbers in the two popular dictionaries.
