Here, 1 point map is constructed first, adding pinyin and Chinese dictionary of Qingdao, jinan and yantai, then deleting Qingdao, and finally checking whether Qingdao still exists

package main

import "fmt"

func main(){

    var pc map[string] string

    pc = make(map[string] string)

    pc["qingdao"] = " Qingdao "

    pc["jinan"] = " jinan "

    pc["yantai"] = " yantai "

    delete(pc,"qingdao")

    qingdao,ok := pc["qingdao"]

    if ok{

        fmt.Println(qingdao)   

    }else{

        fmt.Println(" Elements don't exist ")

    }

}
