In China culture, which plant symbolizes pure character and noble integrity?

"Four Gentlemen" is the traditional theme of Chinese painting, and it is the general name for the four flower themes of plum, orchid, bamboo and chrysanthemum. . Add Lan, and it's called "Four Friends". In the Ming Dynasty, Huang Fengchi compiled Four Spectres of Zhu Mei Lanju, and from then on, Mei Zhulanju was called the "Four Heavenly Kings". Painters use "four gentlemen" to flaunt the noble character of gentlemen. And I think bamboo can best reflect the integrity of ancient gentlemen.
