Was the drunken book in Wang Hu Building written in the morning or in the afternoon?

I wrote it this afternoon. Drunk Book at Wanghu Building on June 27th is a set of seven-character quatrains written by Su Shi, a famous writer and calligrapher in the Northern Song Dynasty, during his exile in Hangzhou. In official website's poems, he said that what the calligrapher Su Shi saw by boat in the afternoon showed the wonders of the West Lake in Hangzhou, which was deeply loved by people.
