主席说我是个好姑凉
[zhŭ xí shuō wŏ shì gè hăo gū liáng]
This username is humorously combining a formal title 'chairman' with casual and cute self-description. '姑凉'(a misspelled word for '姑娘') in modern internet language often used by girls to call themselves as an informal and lovely way, indicating the user wants to appear approachable.
