The reason why Mexico chooses Oaxaca, a relatively niche city, is mainly to see two attractions in a travel note, one is Hierve el agua on the outskirts of Oaxaca, and the other is this church. The former was a little disappointed because the season was wrong and the water was insufficient. But this church and the museum next to it really made me feel that Oaxaca was not in vain. The interior of the church is very beautiful, especially the family tree on the top of the doorway, very spectacular.
