This church is called nhà thờ chánh ta, Chinese abbreviation cathedral, open from 8 to 11 o'clock, 2 to 4 o'clock, no one collects tickets, but there is a merit box at the door, you can voluntarily invest some change to enter. A bottle of mineral water in the small store at the door is very cheap. The church photo is still OK, a selfie stick and tripod can be filmed ~~
