func task() {
    fmt.Println("I am runnning task.", time.Now())
}
func superWang() {
    fmt.Println("I am runnning superWang.", time.Now())
}

func main() {
    s := gocron.NewScheduler()
    s.Every(1).Seconds().Do(task)
    s.Every(4).Seconds().Do(superWang)

    sc := s.Start() // keep the channel
    go test(s, sc)  // wait
    <-sc            // it will happens if the channel is closed
}

func test(s *gocron.Scheduler, sc chan bool) {
    time.Sleep(8 * time.Second)
    s.Remove(task) //remove task
    time.Sleep(8 * time.Second)
    s.Clear()
    fmt.Println("All task removed")
    close(sc) // close the channel
