The following is my opinion.
The key is to have Long Mai before riding a dragon for burial. Riding a dragon is the same as ordinary knot points, so you should pay attention to the dragon needle on the pulse line. If something goes wrong, you can only choose another good place to move and bury.
Riding a dragon is not a good point or can only be used in special families, such as the third generation, from the perspective of geomantic omen, because riding a dragon buries blessings without shading grandchildren.
I hope it helps you.
