I think it is the (Macau) Mazu Cultural Festival

Mazu and Macau have historical connections. The A-Ma Temple in Macau is more than 500 years old and has always been popular.

The cultural relationship between Macau and Mazu has a long history. There are temples dedicated to Mazu in the Macau Peninsula and in Xixietufang, and they all have a history of more than a hundred years. Mazu Pavilion was built in 1488 and has a history of more than 500 years. Mazu Pavilion is backed by mountains and faces the sea, surrounded by towering ancient trees and beautiful scenery. It is a must-see for many tourists. In Mazu Pavilion, smoke is lingering all year round, and many faithful men and women kowtow and pray for blessings. Every year during the Spring Festival and March 23rd of the lunar calendar, Mazu’s birthday is celebrated, which is when the incense in Mazu Pavilion is at its peak. Starting from midnight on New Year's Eve, many faithful men and women come here to worship the gods and pray for blessings. The temple is bustling inside and outside. Before and after the birthday, a large shed will be set up in the open space in front of the temple as a temporary stage to perform Shensu operas.
