            'Doctor and Patient' represents two roles in a medical context: 医生 (yīshēng) means doctor, the healthcare provider; 患者 (huànzhě) refers to the patient, one who seeks medical treatment. The username could imply the complexity of the healer-sufferer relationship or the dual perspectives on medical matters, emphasizing the interconnectedness and mutual dependence of these parties.
