Carlo was reading a book about the cathedral and children gathered around to read with him.
Then the procession began. It started from the cathedral and then went around the square in front of the bell tower. You can see women in their ao dais, beautiful long dresses over pants. The colors represent different Catholic organizations for the parish.
The procession was led by men carrying the traditional celebration flags of Viet Nam found at every festival.
While the big gong and the big drum were being played in the bell tower, the small tam-tam (small gong) and drum were carried with the procession. The drum is male and the tam-tam is female, the same as yang being male and yin being female. Both are needed to make the world. Notice the yellow and white flags, the colors of the Catholic Church.
The band wasn't playing when it came by but we could hear them wherever they were. Their songs have a French flavor as do their uniforms, the influence of decades of French occupation.
You can see better the women, each wearing the ao dai. The colors were spectacular and added to the spectacle.
Here is a video of what happens when the Eucharistic procession stops.
