有一些在路上，有一些下到田里面，距离声源大概 2 米。农村真是太安静了，一点嘈杂的声音都没有。远处有铁路桥，不时有火车开过，有些想去录。九点还有寺庙的钟声，但很远，不知从哪发出来的，下次去的时候一定要找到。
Location: a field in the border of Yizheng and Yangzhou. Some were on the road, some were down to the field, and the sound source is about 2 meters away. The countryside was too quiet, there was no any noise. There were railway bridges in the distance. From time to time, there were trains passing by, and I want to record, a little. There were temple bells at nine o'clock, but very far away.
Divided into four segments: 1, insects, 2, added high-frequency insects, 3, frog sound gradually reaching a climax, 4, separate frog sound
