    "context"
    "github.com/haormj/log"
)
func main() {
    l := log.Logger.Clone()
    l.With("main", "I'm main")
    ctx := log.NewContext(context.Background(), l)
    hello(ctx)
    world(ctx)
    l.Info("main", "end")
}
func hello(ctx context.Context) {
    l, _ := log.FromContext(ctx)
    l.With("hello", "1")
    l.Infow("this is hello function")

func world(ctx context.Context) {
    l, _ := log.FromContext(ctx)

If pass Log through Context, pay attention to the life cycle of the Context to prevent memory increase
