上海 塑山计划：
邀请每一位走进“礐嶨”的观众，从路过的任何地方带来一小撮故土，投递到演唱会门口的收集箱内，与“礐嶨”悄然联结。
Shanghai: Mountain Craft Project
Every attendee was invited to bring a pinch of soil from their hometown and drop it into collection bins at the venue entrance, forging an implicit bond with the core concept of Quexue.
北京 云端山迹：
山不止雄奇，也藏着无数细微却丰盈的局部，值得被感知。邀请观众上传他们眼中有关“山的局部”的照片，在云端汇聚成一座由众人记忆共同构筑的山。
Beijing: Mountain Trails on the Cloud
Mountains feature not only grand peaks but also countless delicate, vibrant details waiting to be discovered. Fans submitted photos capturing their personal glimpses of mountain fragments, which digitally converged into a collective mountain on the cloud.
成都 纸船留念：
山海相逢，后会有期，在巡演最后一场的现场，易烊千玺教观众用印有该场信息的“船票”做一个纸船，让群山与涟漪都记住这场相聚。
Chengdu: Origami Boat Keepsake
Mountains and seas meet, till we cross paths again. On the tour’s final night, Jackson guided fans to fold souvenir paper boats from event-printed slips, letting rolling mountains and rippling waves witness this one-of-a-kind gathering.
