go的浅拷贝

请问arr里面有张三吗？

package main

import (
    "fmt"
    "math/rand"

    "time"
)

type SonSeed struct {
    RtaObject string
}
type FatherSeedStu struct {
    name string
    age  int
    Son  *SonSeed
}

func init() {
    rand.Seed(time.Now().UnixNano())
}
func Seed1() {
    var st *FatherSeedStu
    st = new(FatherSeedStu)
    st.Son = new(SonSeed)
    arr := make([]*FatherSeedStu, 0)
    for i := 0; i < 3; i++ {
        rdn := rand.Intn(5)
        if rdn < 2 {
            st.Son.RtaObject = "张三"
        } else {
            st.Son.RtaObject = "李四"
        }
        temp := *st
        if temp.Son.RtaObject == "李四" {
            arr = append(arr, &temp)
        }
    }
    for k := range arr {
        fmt.Println("---写入:", arr[k].Son.RtaObject)
    }
}
func main() {
    for i := 0; i < 20; i++ {
        go func() {
            Seed1()
        }()
    }
    time.Sleep(1 * time.Second)

}
