The phrase "writing like a golden dragon comes out of the water, stopping like a Cai Feng returning to the forest" is usually used to describe the superb calligraphy or painting skills, which means that the brushwork is vigorous, flexible and free, as lively as a golden dragon comes out of the water; And after finishing the work, the pen collection can be natural, smooth and just right, just as elegant as Cai Feng's return to the forest. Such descriptions are more used to praise the exquisite skills of calligraphers and painters in artistic creation than to describe Peking Opera.
