一、春节

春节是中国最重要的传统节日，也是最长的一天。2021年的春节在农历二月初，正逢新冠疫情防控期间，因此很多家庭选择了宅家过年。虽然不能像往常那样团聚，但人们仍然保持着传统习俗，比如贴门神、挂灯笼、放鞭炮等。政府和企业也提前安排好工作和休息时间，确保民众有足够的时间与家人共度佳节。

二、清明

清明是一个纪念先人的重要时刻，它标志着冬季结束，万物复苏。在2021年的清明期间，由于疫情防控措施，一些公园和陵墓调整开放时间或者实行限流管理，以减少人群聚集。同时，这个时候也是种植树木的最佳时机，不少城市组织了大规模的绿化工程，以此来提升市容环境。

三、中秋

中秋 festival, also known as the Moon Festival or Mid-Autumn Festival, is another important traditional holiday in China. In 2021, it fell on September 21st. Due to COVID-19 restrictions, many families still chose to celebrate at home with mooncakes and watching the full moon together. Some cities even organized online events for people to join in and share their celebrations.

四、国庆

The National Day of the People's Republic of China usually falls on October 1st every year. In 2021, it was celebrated during a time when the country was gradually recovering from the pandemic impact. The government encouraged people to travel within their own provinces or cities instead of going abroad for vacation. Many scenic spots were decorated with red flags and balloons symbolizing national pride.

五、新年

Chinese New Year is just like Christmas in Western countries; it marks a new beginning and fresh starts. In 2022 (the first year after COVID), many Chinese people are looking forward to a more normal celebration without strict lockdowns or travel restrictions. They hope that this year will bring better health and prosperity for everyone around the world.

These holidays play an essential role in shaping Chinese culture by providing opportunities for family reunions, cultural practices, and social interactions among communities despite being affected by external factors such as pandemics or other challenges faced by society today
