Grand Meeting of Physics and Aerospace

Three days later, Beijing had a cloudless, sunny day.

It was rare for this city to have such good weather.

Thousands of people gathered at the Beijing Conference Center.

Two security guards stood at the conference hall entrance with a formal smile on their faces.

Their faces became sore after a while. They spoke to each other in hopes of relaxing their facial muscles.

The guard with a buzz cut said, "I realized that no matter what the conference is, if it has an 'international' in its name, it becomes totally different."

The other slightly older guard asked, "What do you mean?"

The younger guard continued, "Think about it, if they changed it to just the China Lunar Hadron Collider Conference, wouldn't it feel less important?"

The older guard smiled and said, "Why does it matter? The word international only means that we're open to cooperation from other countries. What does this have to do with importance?"
