Yesterday it sounds serious. It rains heavily until the evening. Typhoon Wipha is reported heading Shanghai today. School is closed. People is evacuated. After yesterday evening, suddenly it is quite. No rain, a little bit of wind. I am excited to see what can happen this morning. Now it is after lunch, it is still quite, no rain, no wind. Whoo, Shanghai is safe this round.
