go - Assign a map to another map is safety in golang?

Question

The code like:

    m := make(map[interface{}]interface{})
    //read
    for i := 0; i< 10000; i++ {
        go func() {
            for range m {

            }
        }()
    }
    //write
    for i := 0; i< 10000; i++ {
        go func() {
            mTemp := make(map[interface{}]interface{})
            m = mTemp
        }()
    }

There are 10000 read goroutine access m,and another 10000 write goroutine assign a new map to m, and it's safety?
