Explain in detail:
1, plant: a root that rises and is exposed on the ground. "Mu" means trees; "Zhu" (zhū) represents the form, that is, the way the roots spread out, and also represents the pronunciation.
2. Zhu: the name of the river. A tributary of Surabaya, now in Shandong Province. Shuǐ means water, that is, a river; "Zhu" (zhū) indicates the shape of the river or its tributaries, and also indicates the pronunciation.
3. Beads: [pearls], spherical particles in shells. Milky white, shiny, with sand grains in the center, it is a special Chinese medicine. "Yu" means jade, that is, the external color is like jade; "Zhu" (zhū) means form, that is, radiant appearance, and also means pronunciation.
4. The words "Jiang" and "He" were originally created to refer specifically to the Yangtze River and the Yellow River. Because rivers belong to water, they all use "water" as the ideological part of these two words. Then, according to the pronunciation of calling rivers in spoken language, the phonetic parts of "Gong" and "Ke" are selected respectively, thus forming the two pictophonetic characters of rivers.

Significance of pictophonetic characters:
From the perspective of the development of Chinese characters, the pictophonetic word-making method not only breaks through the limitations of pictographic, referential and knowing words, but also finds a simple method to create words for many things that are pictographic and intentionally difficult to understand. More importantly, it makes up for the defects that pictographic, referential and knowing words cannot be directly labeled.
In order to record the symbols of language, if words can't be pronounced, they are extremely inconvenient to use and therefore can't survive for a long time. Therefore, worldwide, the transition from ideographic notation to phonetic notation is the same law of the development and evolution of all words.
Although China's Chinese characters didn't evolve into pure phonetic characters, because of the invention of pictophonetic characters and the rapid increase of phonetic characters, they soon took an absolute advantage in later Chinese characters, which greatly strengthened the phonetic function of Chinese characters and also showed that China's Chinese characters also developed and evolved according to the same phonetic law, and the pictophonetic characters played a great role.
