The evolution of public opinion with Level 1

	Peak (person)	Peak time	The peak of the network is the peak	The peak of the line is the time of time	The number of times is reduced to zero
Active person	About 30,000	August 2nd	About 40,000	August 5th	August 10th
Neutral person	About 50,000	August 5th	About 90,000	August 5th	August 10th
Negative person	About 60,000	August 5th	About 13,000	August 5th	August 10th
Immune	About 360,000	August 10th
Total			About 300,000	August 5th	August 10th
