If you look closely as the two rockets are fired, you can already see a rain shaft below the cloud they fired the rocket into. It was already a rainshower when they fired rockets into it!

The video is kind of elementary but yes..there has to be clouds for the process to work

"Technicians with the Beijing Weather Modification Office said they fired seven rocket shells containing 163 cigarette-size sticks of silver iodide over the city's skies. They claimed it provoked a chemical reaction in clouds that forced four-tenths of an inch of rain."

They have done it several time, before the Olympics in 2008 for one.

Cloud seeding is defined as the addition of seeding agents into supersaturated air to generate the formation and growth of cloud droplets or ice crystals. Simply put, cloud seeding is when rainfall of a cloud is increased by the addition of chemicals. This method's supreme goal is, dissipating fog, enhancing precipitation, or subdue hail.

My point was not that there were already clouds, but that it was already raining below the clouds before the rockets were released. You can clearly see the rain shaft as the rockets headed toward the cloud.
