Kim Diep also hides a secret

Many families in Vietnam still often use this flower to display on the altar during worshiping occasions or the first days of the month or the full moon days.
Really beautiful isn't it?

I really don't know how to translate this flower into English. The scientific name is Caesalpinia pulcherrima.
This flower hides a secret that is also very interesting and rarely found, that is the main flower branch that bounces 4 more flower branches below and forms 4 directions (corresponding to East - West - South - North) is called the Four Directions of Convergence.
