After a day of rushing around, when I take off my exhaustion, the most healing moment is walking into the bathroom and turning on that rainfall wall-mounted overhead shower head — as dense water flows gently fall from above my head, it’s like putting the warm spring sun and drizzle into the bathroom. Only at this moment do I understand that there can really be an exclusive "sunny sky" above my head, and all this beauty comes from this thoughtful wall-mounted shower head.
