My musical improvisation is always free as in freedom, but there is no guarantee that you will enjoy it, mainly because you may prefer to abnegate the fresh air, the mountain, the river, and all the things which belong to you, then you restrain yourself in the cage and iron chain forever. 我的作品永远都是自由的，但你可能无福享受了。因为你可能更愿意放弃那清风、山峦、河流以及所有本该属于你的一切，然后，将自己永远禁锢在牢笼和枷锁里面。

Well, just in case you wondering, apparently I am not a flat earther. If I were a flat earther, I don't think I would have enough tools and skills to contribute my works to aviation. I don't want to absolutely agree one theory and disagree another. More importantly, I always appreciate the people who contribute their works, tools, codes, or knowledge to me, so I can use them to contribute more and contribute back to others. For example, I used to write the source codes for a directional gyro simulator which can simulate "Transportation Wander" and "Earth Rate" errors. That program works pretty well, and the end results are pretty close to a real outcome from an accurate directional gyro of a Tupolev Tu-154 aircraft.
