According to incomplete statistics,
the number of blind people in China is over 14 million. 
China is one of the countries which has most blind people in the world.
The number of blind people even exceeds the total population of many countries.
But,
why we can barely see blind people on the road?
Hello
Hello
Do you want to cross the road?
Can I cross the road now?
Let me help you.
Where are you going?
I want to go to Haier Road.
Hairer Road?
Mmm
It' s far.
My friend will pick me up.
Haier Road is far away.
Can I cross the road now?
I'll take you there.
Do you want to cross the road?
Yeah, thank you.
You are welcome.
Haier Road is far away.
How do you go there?
Be careful of the step.
Walk slowly.
The road is flat.
Ok 
Go,
don't worry.
There are some problems of the tactile paving. 
Do you know what this road is?
We have already walked across the road.
You are at the intersection,
do you know what the road is?
( Tell him the location and the roads' name)
You are safe here.
Thank you sir.
Don't mention it.
Excuse me,
do you want to cross the road?
Could you help me?
Sure.
Wait for a while,
the traffic light is red now.
(They discuss which direction is more convenient.)
Which direction does your friend come from?
Sorry, I don't know.
Let's go.
Follow me.
Stop here,
wait a minute,
I think you can stand here.
It's a fork here.
Take care.
Go to help this sir.
Hold his hand.
Do you want to cross the road?
Hello
Do you want to cross the road?
Could you do me a favour?
Yeah, let me help you.
Let us take your guide rod.
Can I take your rod to lead you?
Yeah.
Slow down
Walk down the step.
There's a step here.
Ok, let's go.
There's no car.
What are you doing?
This sir can't see.
Thank you
You are welcome.
Well, here we are.
It's the sidewalk.
Mind the step.
Go to the sidewalk.
Ok.
Thank you.
You are welcome.
Be careful.
Do you want to cross the road?
Hello
Wait a minute, it's a red light.
Let's go, it's green now.
You can walk safely.
You can ask the direction here, can you?
Thank you.
(The lady returns again)
Let's go.
I can't leave you alone.
Laoshan garden is not here.
Let's go.
Are you busy? I don't want to bother you.
No, I am not.
Excuse me,
Is this the right direction to go to the Laoshan garden?
It's there.
Is it?
Yes
Ok, let's go.
Thank you.
Put down your rod.
You don't need to use it.
Just walk forward reassuringly.
Walk along this road.
Actually,
we are shooting a short video.
It's a social experiment.
Thank you so much.
You are so kind.
Can I give you a hug?
Ok, bye
I thought you are real blind.
I am waiting here.
Thank you so much.
Bye
I don't go this way.
I should go to that direction.
Thank you.
Bye.
The tactile pavings is not good enough.
The traffic voice prompt is not enough as well.
But you have us.
