According to the legend, in the period of Tran Du Tong Kinh (1341-1369), at the area of today pagoda, there was a common house ( Cong quan) build by the court for receiving foreign ambassadors. Because most of them followed Buddhism, the King allowed to found a pagoda named Quan Su next the common house for ambassadors to come to pray. Afterwards, the common house was damaged while the pagoda has been existing til now.
It's an active pagoda and usually thronged with
worshippers; the interior is dim and smoky with incense. To the rear is
a school of Buddhist doctrine. For good luck (or for fun), visitors of
any stripe are welcome to buy sticks of incense and make offerings at
the various altars and sand urns. It's easy to just follow suit, and
folks will be glad to show you what to do.
