    America is a mobile society. Friendship between Americans can be close and real, yet disappears soon if situations change. Neither side feels hurt by this. Both may exchange Christmas greetings for a year or two, perhaps a few letters for a while, then no more, If the same two people meet again by chance, even years later, they pick up the friendship.

    This can be quite difficult for us Chinese to understand, because friendship between us flows more slowly but then may become lifelong feelings, extending (延伸) sometimes deeply into both families.

    Americans are ready to receive us foreigners at their homes, share their holidays and their home life. They will enjoy welcoming us and be pleased if we accept their hospitality (好客) easily.

    Another difficult point for us Chinese to understand Americans is that although they include us warmly in their personal everyday lives, they don't show their politeness to us if it requires a great deal of time. This is usually the opposite of the practice in our country where we may be generous with our time. Sometimes, we, as hosts, will appear at airports even in the middle of the night to meet a friend. We may take days off to act as guides to our foreign friends. Americans, however, express their welcome at home. But they truly cannot manage the time to do a great deal with a visitor outside their daily routine. They will probably expect us to get ourselves from the airport to our own hotel by bus. And they expect that we will phone them from there. Once we arrive at their homes, the welcome will be full, warm and real. We will find ourselves to be treated hospitably.

    For Americans, it is often considered more friendly to invite a friend to their homes than to go to restaurants, except for purely business matters. So accept their hospitality at home!

The Terracotta Warriors, one of the eight wonders of the world, have enjoyed international fame. Located in Xi'an in northwest China's Shaanxi Province, they are warriors of the first-ever emperor in1China or Qin Shi Huang in Chinese, Ying Zheng.

Even though I knew they are life-sized sculptures (雕塑), I was still2 when I saw them. I was lucky enough to3 the pit (深坑) and take a close look at them for the first time.

They were made around 2, 200 years ago. When I first got down into the pit, the sculptures scared me4some of them lacked body parts.

I was told that the Terracotta Warriors are not easy to preserve (保存;保护) for over thousands of years. But to my surprise, they were actually5 in color when they were first discovered. However, the color fell off6after being exposed in the air.

The difficulty of preservation is one of the reasons why they have stopped7out other pits. Although the Terracotta Warriors are breathtaking, they are only part of the Mausoleum (陵墓) of the First Qin Emperor.

Shen Wenxi, an expert and museum librarian of the Chinese Academy of Social Sciences, told me there's an even grander area8 man-made mountains, rivers and seas inside the emperor' s underground palace.

However, there is no plan to dig them until there are perfect9of protecting and preserving them. Experts are still busy restoring the relics (修复文物) that were10in the 1970s.
