In recent years, the Cultural Tourism Group attaches great importance to the construction of clean cultural tourism routes, from the initial "clean Jiacheng Hui" theme Party Day activities to the exploration of "Breeze Lecture Hall", "South Lake · Chuxin Lecture Hall" water class ", "Chuxin Post Office" and "Qingfenglian transport" water bus, etc. Then to the innovative development of "South Lake Breeze line" immersive boutique line planning, "clean letter", "water cheap class", "Construction site Art Party (clean) class", etc., to the "South Lake Breeze Line" clean culture brand with mature operating mechanism, the clean tour line continues to circle fans. In particular, the "South Lake Breeze Tour" has attracted Party members and cadres from all over the country to the South Lake to feel the red mark and clean culture through immersion in creating standardized teaching links such as "the first heart to realize the integrity", "the history to ask the integrity", "the oath to feel the integrity", "the message to promote the integrity" and "the Party lessons to learn the integrity". In 2021, the "South Lake Breeze Tour" special line received more than 1,300 batches, about 40,000 people, and carried out 455 batches of Party (clean) lessons, realizing 365 days of Party lessons.
