What's the difference between "long summer" and "summer solstice"?

The difference between long summer and summer solstice lies in time, characteristics and temperature. The time of long summer is May 5 or May 6. Long summer says that the temperature rises in summer, and the time is June 2 1~22, which is the longest day, the shortest night and the higher temperature.

Summer is the first harvest season in all seasons. Summer is the season of nature, life, passion and harvest. On the solstice of summer, the sun shines directly on the Tropic of Cancer, which is the longest day of the year in the northern hemisphere, and it takes about 14 hours from sunrise to sunset in the southern region. Although summer solstice has the longest day and the highest angle of the sun, it is not the hottest time of the year.
