姓
姓 – Xing4 – Surname
In Chinese, some sentences no verb. For example, Jenny might have said 我姓余 – Wo3 Xing4 Yu2 – I Surname Yu — My last name is Yu.
Now both of our 姓 is Minutillo. You can be cute and shorten that to 米 – Mi3 – Rice. Sometimes 三喵 calls me 米先生 which means Mister Mi. I like that.
(Interestingly the way you say Mister is 先生 – Xian1 Sheng1 – First Born. I wonder why that is?)
(Also interstingly, inside the character 姓 you find 女 – Nu3 – Woman and 生 – Sheng1 – Born.)
