Breathe in the crisp air of the mountain stream, footsteps follow the undulating heights between the mountains and the sea, Hong Kong Island shrouded in light mist, overlooking like a bird's nest, walked three kilometers then five kilometers, five kilometers then seven kilometers, as the crescent moon hangs up, only then does the return journey begin, after a trip out, it feels like enjoying the coolness of air conditioning while mining is still the best.
