What events did Li Tianxi and Lee Hyo Ri take part in when they traveled to Jeju Island for three days and two nights?

It is called Golden 12, and it is a program planned by Lee Hyo Ri to promote the concept of environmental protection and animal protection. She is the main one. Invite friends who have a good relationship with her and are enthusiastic about animal protection to be members once a week and do some meaningful activities. Going to Jeju Island is one of them, and Tianxi is an invited guest, not a full member. If you want to watch it, you can watch it directly in the potato search "gold 12" ~ quite a good program.
