Golang报错： more than one character in rune literal

package main

import "fmt"

func main() {
   const (
      BEIJING = '北京'
      SHANGHAI = '上海'
   )

   fmt.Println("BEIJING:",BEIJING)
   fmt.Println("SHANGHAI:",SHANGHAI)
}

报错：

# command-line-arguments
more than one character in rune literal
more than one character in rune literal

原因单引号，双引号的问题，在go语法中，双引号是常用的来表达字符串，如果你使用了单引号，编译器会提示出错。
