Hang Pictures on a Wall

Because I want to know how it feels to hang pictures on a wall
Sleep in the same bed at night
I want reasons to stay
I want someone to take up my time,
And miss me when I go

I want a home

利用 GDP 数据理解「到 2050 年中国争取要达到中等发达国家水平，基本实现现代化」

Comparisons of national wealth are frequently made on the basis of nominal GDP and savings (not just income), which do not reflect differences in the cost of living in different countries (see List of countries by GDP (nominal) per capita); hence, using a PPP basis is arguably more useful when comparing generalized differences in living standards between nations because PPP takes into account the relative cost of living and the inflation rates of the countries, rather than using only exchange rates, which may distort the real differences in income. This is why GDP (PPP) per capita is often considered one of the indicators of a country’s standard of living,[3][4] although this can be problematic because GDP per capita is not a measure of personal income. (See Standard of living and GDP.)

Armory Show：下午五点，我们重新开始

Lee Kit 是个来自香港的创作者。他的作品，通过简单的诗句传达出绵长的思绪。有点难过、有点安静、有点寂寞，再加上色块与颜色的条带让人觉得舒服。作品中，无论是被挖开的那种感觉，还是不断划动导致凹下去的那种层次感真是很触动人，很容易引发我的共鸣。
