在电视连续剧《雪城》主题歌中，有句“天睛别忘戴草帽”的歌词。慎咀细嚼，可以让人得到这样的启迪：居安当思危，祸患不临门。曾记得，过去在农村一般是用草帽避雨的。“天有不测风云”，特别是在夏季，有时初看天气晴朗，说不定转眼间就乌云密布，风雨大作，把人淋个“落汤? In the TV series “Syracuse” theme song, there is a “Do not forget to wear straw hat” lyrics. Shen carefully chew, you can get such inspiration: live in danger, evil does not come. I remember that in the past, straw hat was generally used to prevent rain in the countryside. “There are unexpected events in the sky,” especially in the summer, and at first glance the weather may be cloudy at first glance. Maybe it is an overcast cloud and a storm of wind and rain.
