胸大无脑銱大头小
[xiōng dà wú năo diào dà tóu xiăo]
This nickname uses exaggerated physical descriptions to create a humorous effect. 'Large chest but brainless' refers to appearances being misleading. While 'big-headed dwarf' implies looking odd due to disproportionate body parts. It should be noted that the use of such nicknames might not always be appropriate as it could promote negative stereotyping.
