1. The face can speak a thousand emotions, but it can easily mask what the heart feels. for the happiest face may be masking the most hurting heart.
2. He who smokes never smells his own smoke, just like the loved one never knows how hard the one who loves you is. ???
3. Describe a good law in your country.
---What it is?
---How did you knew it?
---Who does it affect?
---Why is it good?
I am going to talk about the first law that comes into my mind.
It is stipulated in the Chinese Constitution that civilians are prohibited from carrying guns or weapons of the same sort. I think it was put into the Law by our founding fathers since the establishment of our nation the People’s Republic of China.
I guess I have always known it. However, I wasn’t aware of it only until I read news about the school shooting incidents in America about a random person entering a campus. And out of the blue he shot and wounded a dozen innocent students. After reading the news, I was suddenly struck by a fact that has been lurking in mind and has been neglected: Hey!!! It is illegal to own a gun or even bullets in China!!! How about that!!!
This law affects all Chinese and even foreign visitors who are currently staying within Chinese borders. It guarantees a safe environment for all of us. Before the PRC was founded, our county was crawling with thugs and mobs who claimed lands as their own using violence. They used weapons such as rifles. However, after the implementation of this law, crime rates had decreased year by year and mobs of rebels were forced to break apart.
It was a visionary and standing-ovation worthy decision. Thanks to this law, we are able to stroll down the dark night streets with fears only for ghosts and not for having our lives taken by money-seeking thugs. Thanks to this law, there are no concerns of one person causing casualties by the dozens and dramatizing those who survive. Again, thanks to this law, now if I run into a mugger, I have a fighting chance! After all, a shiv is not a gun. I could out run a shiv but never could I out run a flying bullet!
4. Sometimes I really want to forget you, just remember that in this world. However, I often forget the whole world, just remember that you. ???
5. We live alone, we die alone. Everything else is just an illusion.
6. Sometimes it is sunny and sometimes overcast. This is life. Do not pray for easy lives, pray to be stronger. By constant self-discipline and self-control, you can develop greatness of character.

Abstract
Developing and testing algorithms for autonomous vehicles in real world is an expensive and time consuming process. Also, in order to utilize recent advances in machine intelligence and deep learning we need to collect a large amount of annotated training data in a variety of conditions and environments. We present a new simulator built on Unreal Engine that offers physically and visually realistic simulations for both of these goals. Our simulator includes a physics engine that can operate at a high frequency for real-time hardware-in-the-loop (HITL) simulations with support for popular protocols (e.g. MavLink). The simulator is designed from the ground up to be extensible to accommodate new types of vehicles, hardware platforms and software protocols. In addition, the modular design enables various components to be easily usable independently in other projects. We demonstrate the simulator by first implementing a quadrotor as an autonomous vehicle and then experimentally comparing the software components with real-world flights.
