About the 5th,6th and 7th pictures at the bottom

The temple in the 5th picture (img106b) and the two pictures showing
wall details and incenses is actually not a Buddhist temple, but the 
Temple of Le Van Duyet, very popular in Saigon.

Noble Le Van Duyet was a commanding army general in the court of Nguyen Anh,
the last king of Vietnam just before the arrival of the French. According to
legend, Le Van Duyet was a patriot, frank and close to the people; his death
was suspectedly a plot in the king's court. A suspicious death of a good man
close to the people explains the devotion to his memory by people in South VN
through hundred years until today. 

A tradition observed by thousands of people in Saigon is to come to the
temple during Tet, the New Year feasts, to pray for his protection, but also
to ask for his advice by "Xin Xam". The following 2 pictures show large
incences most seen during those feasts, which last several days...

Thanks for the pictures that bring back lots of emotion.
