there's a moving inscription of a whatsapp chat supposedly between a firefighter going for assistance and his friend.
thanks to /r/DrSalted on Reddit, it roughly translates to this:
1:48 am
Fireman:
Are you here bro?
Friend:
Here, Here
What happened?
1:52 a.m.
Fireman:
My phone can’t get any calls out
Gangzi just passed away
He died, He died
1:53 a.m.
Friend:
Are kidding me?
Where are you?
Fireman:
I’m in the car to Tanku… Tangu
Friend:
Please call me right now
Fireman:
I’m wearing all my gear, I’m the only person with a phone
Friend:
Then please call immediately me tomorrow when you get home
Fireman:
If I don’t come back, My father is your father
Remember to visit my mother’s grave
Friend:
OK, your dad is my dad
Please take care

at this point, it rests no doubt in my mind that the chinese government is covering the actual death toll, as it has been reported that over a hundred firefighters went in the place when it was just catching fire, before the huge explosions we've witnessed, and only 4 came out. 50 is too much of a low estimate for this horrible catastrophe.
