Literature Reference: 鱼鲁非难识，铅黄自嬾持。—— 《酬翰林白学士代书一百韵》 The distinction between 'fish' and 'Lu' is not difficult; the yellow lead is held carelessly. Source from 'Chou Hanlin Bai Xueshi Daishu Yibai Yun'.
鱼:
Fish. When used in a name, it symbolizes a bright future and carries the meaning of prosperity and auspiciousness.
鲁: The taste of fish is exquisite and delightful. When used in a person's name, it metaphorically signifies that one who attains profound knowledge can achieve a seamless integration of understanding and possess a far-reaching vision.
