Forget to Cross the Forget River

A dilapidated train keeps driving in a fog... Several passengers fell asleep motionless and sat on their seats... Who is awake? Who was the first to see... See this piece of "infinite"... The fog has cleared, where is the way back? … Wangchuan is a river. Those who cross the River of Forgetfulness will forget everything. But Lin Wang couldn't get over it. He just approached the river again and again and then left. Because he was afraid of forgetting why he wanted to cross the river. —— Inscription
