重阳节是中国传统的节日之一，通常在农历九月初九日庆祝。人们会爬山、赏菊、吃重阳糕等活动。这个节日与老人有关，因为“九”与“长寿”谐音，所以人们也会在这一天尊重和祭拜祖先，探望长辈。The Double Ninth Festival is one of the traditional Chinese festivals, usually celebrated on the ninth day of the ninth lunar month. People will go hiking, appreciate chrysanthemums, and eat Chongyang cake. This festival is related to the elderly because 'nine' sounds like 'longevity', so people also respect and worship ancestors, visit the elderly on this day.
