How does Emperor Qian Long indirectly insult King George III?

Emperor Qianlong indirectly insulted King George III by dismissing his request for trade and diplomatic relations, suggesting that China had no need for British goods or influence. In his letter, he referred to the British monarch as "a petty king" who ruled over a small territory, contrasting it with the vastness and superiority of the Qing Empire. This implication of China's cultural and political preeminence served to undermine the British monarch's status and authority.
