Ming China: spring snow ruins the wheat in 1453; deep snow and frozen sea in winter 1453 to 1454

Mingshi volume 28: Jingtai 4th year, 2nd and 3rd months (about March to April 1453), at the eight garrisons of Fengyang 'rain and snow did not stop, damaging the wheat'. From the 11th month of that year to the next spring, snow several feet deep in Shandong, Henan, Zhejiang and the capital region, the sea frozen 40 li out, tens of thousands of people and animals frozen to death; in the 1st month of 1454, 40 days of snow south of the Yangtze. The Mingshi has no dim or red Sun for 1452 to 1453; the Wikipedia phrase about 'dust obscuring the sunlight' is not in it.
