The Temple of Heaven park is massive. There are gorgeous buildings throughout the grounds including the iconic Hall of Prayer for Good Harvests, built in the 1400s. It was here that for centuries, the Emperor of China would visit each year, abstaining from meat, to pray for healthy crops. As you enter the main temple, admiring the 12 pillars representing the months each year, you are handed a red scroll with a proverb on it. This is your first puzzle. You must decipher a passphrase to earn a set of calligraphy brush strokes.
