erm, ghosts gate open is bit chinese folk believe de. they
are around everyday. no need to open any gate. :)
but i think the more people believe the more they become more
active though. recite also good. more better, everyday. :)
ps: though Di Zang is more related to hell, while ghost and hell
relation, i am still figuring.

oh haha yes u are right... but i try not to divert or slanting
towards the attention to this ghost gates thingy
what i meant is to use this opportunity to chant DiZang sutra,
dedicate merits to all sentient beings 
why Di Zang is so popular among the Hells... not too sure, could
be due to chinese folks belief
Di Zang is thought to be benefitting all realms, especially for
the devas too
