S21E5: Tea, Roof Finials, Artificial Flowers, Alloy Wheels

Fresh tea leaves are picked, withered, rolled, oxidized and dried to develop their flavour and aroma. Decorative roof finials are shaped and finished to withstand the weather; fabric petals and leaves are cut, coloured and assembled into artificial flowers; and molten alloy is cast, machined and coated to produce lightweight vehicle wheels.
