My work is working on
paleontology,you know,
fossil mammals. My father actually, he was a
a geologist,
so when I was a kid, like a seven or eight-year old he always 
brought me with him to the mountain
where he'd do the geology, and also
where are I
live, my home, my family which is in south China
and there's a Museum of Natural History across the street,
so after the school I usually went to that museum and looked, and looked around
a bit at their display and I'm
particularly interested in  the early
evolution of mammals.
By early I mean those living about 
two hundred million years ago to about
thirty million years ago. So its a long
geological history.
We all do fieldwork
and as a paleontologist and that's one
of you know the interesting parts to be
paleontologist because we have the
opportunity to go to those remote areas
in the Gobi Desert. Working in that area it's always, that kind of story I can tell
you, I can spend a whole day to tell you
that at this story but I'll tell you one
whatever reason in that year we
rented a two wheel drive vehicle,
the driver is a little
careless, and we said, you know,  stop stop, you know, this is an outcrop, there is a cliff
right in front of us
and he said, well that's alright and he
just drove like ten meters far
away
and the vehicle got stuck. It was in the
middle of the day, the temperature is about
110 degrees or something,  it's very hot
and we are more than a hundred kilometers away from where we live. 
You can die if you don't know
where you are, if you don't know how to
deal with that.
Fortunately, these days
we can use Google Earth to know the surrounding area, where
you can find anything.
So in that particular case we know to the north
there is the water canal 
and fortunately after we walked about ten kilometers we got the cell
phone
signal
and that we called Beijing to call our
colleagues in Beijing and then tell us
you know local people's telephone number.
We called the local people
and they sent a vehicle to us. We made it, and we were eventually
very happy
that we didn't get into any 
serious trouble. 
For all of us
we already have something in our minds which, I call, you know, that's my dream
so every time when I go out there, in my 
mind
I will say I hope I will find this, find that, find that. Sometimes, you know,
it's  better to be, you know,
lucky than to be smart, in a way, those specimens,
it's just 
just by chance preserved and
I happened to be the person who
noticed that and studied that.
In a way I have to try very hard
to find those, but on the other hand,
you know, you are lucky to find it.
