However , to everyone s delightful surprise , it began to rain on the afternoon of the first day of an annual exhibition where master s teachings were introduced . in fact , the rain did not stop until late that night . the rain had not only relieved the drought in the water - shortage areas , but also had eliminated the dustiness at the exhibition venue 然而令人十分惊喜地，当师父教理在一个年度展览会中宣扬的首日下午，降下了难得之甘霖，直下到夜晚才歇，这场大雨解除了缺水地区的旱象，同时也让明日的展览会场不再风沙飞扬。
