在golang中使用string [] []时，复合文字中的类型丢失

This is my code:

package main

import (
    "fmt"
)
type person struct {
        //name  [][]string{};
        name [][]string
    }  

func main() {
var people = map[string]*person{}

people["first person"] = &person{name:{{"My name","30"}}}
    fmt.Println(people["first person"])
}

I have an error:

missing type in composite literal

[[My name,30]]

Could someone help me?
