The Chinese word "讳疾忌医" is formed by combining four characters into two parallel verb-object phrases: "讳疾" meaning "to conceal illness" and "忌医" meaning "to avoid doctors", where "讳" (conceal) and "忌" (avoid) are verbs acting upon their objects "疾" (illness) and "医" (doctor) respectively, resulting in a compound phrase that literally expresses the act of hiding sickness and shunning medical treatment.
