Mr. Zhang Yonghe's original design intention is to highlight the architectural style of Xiangxi dwellings and imitate the style of Xiangxi Diaojiao Building and Gallery. He may have overlooked the climatic factors that Xiangxi is located in Wuling mountain area, with continuous rain and insufficient light all the year round, so that the lighting inside the building is seriously insufficient. If it's sunny, it's really scary not to turn on the lights on cloudy days.
