爱笑着逞强
[ài xiào zhe chĕng qiáng]
This could be interpreted as laughing to cover weakness. '笑 (smile or laugh)' often conveys happiness and ease, while here it combines with '逞强 (trying to appear tough), showing pretense of being strong when actually weak. Such behavior usually occurs under pressure. People smile outwardly as a self-defense mechanism to hide real hardships, vulnerabilities, pains, or worries, reflecting the inner struggles and challenges of the creator.
