为什么当我们使用struct引用结构时(*structObj)，Go似乎会返回的新副本，structObj而不是返回原始的相同地址structObj？这可能是我的误解，所以我要求澄清

package main

import (
    "fmt"
)

type me struct {
    color string
    total int
}

func study() *me {
    p := me{}
    p.color = "tomato"
    fmt.Printf("%p\n", &p.color)
    return &p
}

func main() {
    p := study()
    fmt.Printf("&p.color = %p\n", &p.color)

    obj := *p
    fmt.Printf("&obj.color = %p\n", &obj.color)
    fmt.Printf("obj = %+v\n", obj)

    p.color = "purple"
    fmt.Printf("p.color = %p\n", &p.color)
    fmt.Printf("p = %+v\n", p)
    fmt.Printf("obj  = %+v\n", obj)

    obj2 := *p
    fmt.Printf("obj2 = %+v\n", obj2)
}

输出量

0x10434120
&p.color = 0x10434120
&obj.color = 0x10434140   //different than &p.color!
obj = {color:tomato total:0}
p.color = 0x10434120
p = &{color:purple total:0}
obj  = {color:tomato total:0}
obj2 = {color:purple total:0} // we get purple now when dereference again
