The lowest point of sentiment this year was exactly the end of early April, with the largest rebound and the longest duration in the 4.7-5.14 time range. Then there is the junction of late June to mid-late July. August is currently shorter. Strangely, the three emotional highs and lows (emotional highs and lower emotions, higher and higher) form an emotional triangle convergence. It is estimated that when everyone hears this word for the first time, it is generally a K-line triangle convergence.
