China hasn't only existed for one day. Now, the whole nation has become richer and it's become a problem. The problem is universal. The factor is big. Everybody has to rethink the balance of the world and the whole landscape.
There's no use in comparing one's feelings between one day and the next; you must allow a reasonable interval, for the direction of change to show itself.
Perhaps man has a hundred senses, and when he dies the five senses that we know perish with him, and the other ninety-five remain alive... Everything that is unattainable for us now will one day be near and clear... But we must work.
Every day, there's that tension and the pressure. Each scene that you shoot is like getting to that next step, but there's still that mountain to climb. So it's not like one day is harder or one scene is harder. They are all equally challenging.
