The First Hole in one - Long 180-Yard Uphill Hole

Long 180yd par 3 uphill two tier green. I hit badly with little hook, but fortunately the ball hit the hill from right side bunker and bounced to the green. I couldn't see my ball got into the hole because of elevated green. When I got up to the green, I looked for the ball and cannot find it. After 1-2 minutes, the other player said "check the hole," and I found my ball. First eagle and first hole in one in my life.
