If you don’t act, the danger becomes stronger.

I think we cannot have a double standard. We cannot see our art as different from the reality. We cannot use two different sets of judgment.

The United States is a melting pot. Like John F. Kennedy said, it's a nation of immigrants. But Donald Trump wants to build a fence that clearly makes the statement: "You and I are divided. We're different, and you're dangerous." That kind of thinking stops human, civilized evolution. It's dangerous to create that kind of tension.

I think optimism is whether you are still exhilarated by life, whether you are curious, whether you still believe there is possibility.

The idea to use backpacks came from my visit to Sichuan after the earthquake in May 2008. During the earthquake many schools collapsed. Thousands of young students lost their lives, and you could see bags and study material everywhere. Then you realize individual life, media, and the lives of the students are serving very different purposes. The lives of the students disappeared within the state propaganda, and very soon everybody will forget everything.

Nationality started as something natural, but we should not be restrained by the old politics that make up these clear lines. It should have its own way of evolving. In some places, it will evolve slower and in others, faster. It's like the mountains, the ocean and the rivers. It has its own geological forms. Societies cannot be flat. But during change, human rights, human dignity and free speech have to be protected. Otherwise, we'll be going backward.

The whole attitude of society has become much more open and realistic. They realize that the only way to make a more democratic and free society is to let different opinions come out.
