Here is the original article：《说文解字》中的会意字调查分析作者：李野尘
Associative in that the two parts of the Chinese characters with one part meaning, the other part about figure. Let's take the first example: xiū 休 rest
The left of this character xiū 休 rest is the radical of a person. The right part of this character means 'tree' （denoted by 木）
Hence it is like a man leaning against the tree, having a rest. Especially back in the ancient times, people worked in the field. When they rest, it is next to a tree. Using this Chinese character, you can think of this scenario instinctively.
The second example is dàn 旦 daybreak or dawn.There is an upper and lower part of the character. The Upper part is“rì 日 the sun,” and the lower part is like the horizon line 一 . This character is easily remembered when you think of the sun rises from the horizon (ie the line), thus it's daybreak.
The third example is nán 男 male or man.
The upper part of this character is “tián 田 farm field ” and the lower part is “lì 力 strength,” You can easily understand the meaning of this character if you consider that people working in the field with strength are mostly men.
