When it's cold in summer, wearing short sleeves and wearing a scarf will make people laugh and feel corny?

Don't! I remember once seeing an old man practicing Qigong on TV, wearing a cotton-padded jacket in summer and short sleeves in winter. Dress differently, and others may envy you. Look, this guy is also practicing his powers! Of course, this is a joke. The body is your own. Self-knowledge. Wear your own clothes and let others talk!
