The Alishan region in Chiayi is known for its tea plantations situated between 1000 to 1800 meters above sea level, producing tea commonly referred to as Alishan tea. The area's high mountain climate, frequent mist, significant temperature variations, and shorter daily sunlight compared to lower altitudes contribute to the distinctive brisk and mellow taste of Alishan tea.

In the earlier days when transportation was challenging in rural communities, many relied on traveling long distances on foot, crossing mountains and hills. Kind and warm-hearted Hakka farmers would set up large bowls of tea along the way in pavilions, sprinkling cleaned rice husks inside. Passersby would use a ladle to push aside the rice husks before scooping and drinking the tea. The purpose of the rice husks was to allow weary travelers to catch their breath before drinking, preventing them from consuming the tea too hastily. This tradition is the origin of the term "Feng Cha" or "offering tea."
