I am living in Beijing which has 30 million residents and millions of temporary workforce. However, Beijing also has the most spacious downtown area around the world, I suppose. So the population density could be acceptable. --Is there a crowded place near where you live? --Indeed, there is. I lived near by the Summer Palace, which is one of the famous Chinese sightseeing point, and of course, it's always crowded all through the year. --Do you like crowded place? --Definitly no. There are times that I find I feel panic and lack of reassurance when amongst a turbulent crowd. I have no clue with it, but it really lead me to keep crowd away from myself. --Do most people like crowded place? --oh, you really stumped me. Since you rarely find someone who dislike it in a crowded place but someone like it. The only way that you can gain a relatively exactly answer about that, is to conduct a wide range of investigation with random sample selected. --When was the last time you were in a crowded place? --Maybe the summer palace again, I thought. I went there in the middle of April, and the spring landscape was wonderful. Imagine you are wandering in a moderate weather, properly sunlight and breeze, with perfect scenery in distance. Pretty hills and turrets, tremendous lake with waves surf on it, colossal splendid palace which was for emperor, that's worthy to plunge into a crowded pavement.

I sing song whenever and wherever I want to. I have a fondness for music and rhythm, the lyrics can also transfer affections as well as poems, as which is a revival of poems I believe. Have you ever learned how to sing? In fact I haven't learn it intentionally, but my mom does. She always likes to share the new skills that she learnt to me, but I really rather to be a layman, just following my own skills. Who do you want to sing for? Absolutely for myself. It's me who really appreciate my voice and can conscious of subtle changes of my singing. It's a divine gift that I give to myself every single day, as with no need to show it to others because I can really do without any applause or admiration. Do you think singing can bring happiness to people? Indeed, as I mentioned earlier, music and lyrics can deliver other's affection to you, as painting and literature have done. Imagine that you can reach one's emotion even after he or she died over tens or hundreds of years. That's an extension of human being's civilization and that's why we call them art.
