After do more research about visualisation, I find they always have a clear guide for audience.

I begin to do more research about visualization and meditation, and I find about a vision board; the below two articles hold different opinions, most people support it, but some people think it will make people waste time, in my opinion, the fast-developing business environment totally controls them, dreaming is a shame for them.
Anyway, the original idea of this is to encourage people to work hard and get energy, but my opinion is to let people slow down for a while and just enjoy; our aim is different, so my next intervention name will not be vision board, it may be relaxing board.

After collecting relevant images and pictures of people, I can try to build a community. Corona Flower Show is a good reference.
