Su'er （玊尔） was the theme of Jackson Yee's solo concert held in 2019. Su means flawed jade, and er means you. Coincidentally, the combination of these two characters forms the Chinese character Xi（玺）, which is part of his given name. Su'er conveys the idea of embracing imperfections and accepting your genuine, passionate and one-of-a-kind self. He illustrated two sides of human personality through red and white.The red side stands for the inner true self — sincere, passionate and unpolished.The white side represents the external self shown to the public under social expectations. He stated on stage: "Both flaws and virtues together make you uniquely yourself."
