    One year, on the morning of the thirtieth day of the Chinese New Year's Eve, the little fart set off firecrackers (the little fart lit the small cannon and threw it into the crack of the prefabricated board covering the sewer), detonating the gas in the sewer, and the 15-centimeter-thick, two-meter-long, and one-meter-wide cement prefabricated slabs on the more than 30-meter-long sewer were all overturned, and it was the thirtieth day of the Chinese New Year's Eve, and it was near the bus stop.
