Chinese dragon, as for me, is a symbol of China. Sometimes we use the term "Descendants of the Dragon" (龙的传人) as a sign of ethnic identity. There is a famous song called “龙的传人” sang by Nicholas Tse(谢霆锋). It was very popular when I was young. The lyric writes “there is a dragon in the far east. Its name is China”. I even sing it in my heart when I am typing.
When I was young, I watched many TV plays. There are four major Dragon Kings, representing each of the Four Seas: the East, South, West and North Sea. Because I live near the East Sea, so sometimes when my dad was too hard on me. I imagined myself being the cute daughter of the Dragon King of the East China Sea, and being placed in foster care here. One day, the Dragon King dad will come and take me home. Lol. Why he’s so late?
Why Gentlemen regard virtue as jade？
Confucius said, "Jade is precious not because it is rarer, but because the quality of jade corresponds to a gentleman's virtue.
It corresponds to such virtues as benevolence, wisdom, righteousness, propriety, loyalty, and trustworthiness, and it also corresponds to the ways of the heaven and earth.
Jade is mild and gentle, just like a gentleman's benevolence;
Jade has a fine texture yet it is solid, just like a gentleman's wisdom, his careful, meticulous and thorough way of handling things.
Though jade has edges and corners, it is not sharp and will not hurt others, resembling a gentleman's sense of justice and uprightness.
When the jade is hung, it symbolizes a gentleman's polite restraint and prudence. (I think that’s because in ancient China, people would take jade with them, usually hanging around the waist. When they walk, the jade will make a sound, a gentleman will control their own pace, so the sound is beautiful. People who are not gentlemen will run and jump wildly, and the sound of jade will not be pleasing to the ear.)
When it is struck, it releases a clear and spirited sound, akin to the nature of music.
Though jade is beautiful, blemishes are also obvious, but they will not obscure its merits. Just like a gentleman's loyalty, it's without bias and without a need to conceal.
《礼记·聘义》中孔子和子贡论玉，子贡问孔子，为什么玉比其他的宝石要贵？是因为玉比较少的原因吗？
孔子回答他：不是因为其他宝石的数量多，因而就轻视它；也不是因为玉的数量少，因而就看重它。
从前的君子，都是拿玉来和人的美德相比：
玉的温厚而又润泽，就好比仁；
填密而又坚实，就好比智；
有棱角而不伤人，就好比义；
玉佩垂而下坠，就好比礼；(可能是因为在中国古代古人会戴玉，通常会挂在腰间。走路时玉就会发出声音，君子识礼，走路时会控制自己的步伐，玉的声音很好听。非君子的人会乱跑乱跳，玉的声音就不美好)
轻轻一敲，玉声清脆悠扬，响到最后，又戛然而止，就好比动听的音乐；
既不因其优点而掩盖其缺点，也不因其缺点而掩盖其优点，就好比人的忠诚；
光彩晶莹，表里如一，就好比人的言而有信；
宝玉所在，其上有气如白虹，就好比与天息息相通；
产玉之所，山川草木津润丰美，又好比与地息息相通
