耳顺：
1、（书）《论语·为政》：‘六十而耳顺。’指年至六十，听到别人的话，就能深刻理解其中的意思。后来用‘耳顺’指人六十随。
According to Analects·Governance, 'A person at sixty years of age will thoroughly understand the meaning of others' words.' The phrase '耳顺' later came to mean 60 years old
e.g. 年逾耳顺
over 60 years old
e.g. 耳顺之年
at the age of 60
2、顺耳
pleasant to the ear
e.g. 这个唱腔我听着到耳顺。
This kind of singing sounds pleasant to me.
