. About four m etres l ong, the room served as a sm al l recepti on hal l for im portant vistors. Later, Catheri ne Ⅱ had the Am ber Room m oved to a palace outside St Petersburg where she spent her summ ers. She tol d her artists to add m ore detai l s to i t. In 1770 the room was pl eted the way she wanted. Alm ost si x hundred candl es li t the room , and i ts m i rors and pi ctures shone li ke gol d. Sadl y, al though the Am ber Room was si dered one of the wonders of the worl d, it i s now m i si ng. In Septem ber 1941, the N azi army was near St Petersburg. This was ati m e when the two countri es were at war. Before the N azi s coul d get to the summ er pal ace, the Russians were abl e to rem ove som e furni tures and sm al art objects from the Am ber Room . H owever, som e of the N azi s secretl y stol e the room itsel f. In l ess than two days 100000 pi eces were put i nsi de twentyseven wooden boxes. There i s no doubt that the boxes were then put on a trai n for Konigsberg, whi ch was at a tim e a Germ an ci ty on the Bal tic Sea. After that, what happened to the Am ber Room rem ai ns a m ystery. Recentl y, the Rusi ans and Germ ans have buil t a new Am ber Room at the summ er pal ace. By studyi ng ol d photos of the form er Am ber rom, they have m ade the new one looke l ike the ol d one. In 2020 it was ready for the peopl e of St Petersburg when they cel ebrated the 300th bi thday of thei r ci ty. A fact of an opi ni on What i s a fact? Is i t som ethi ng that peopl e bel i eve? N o. A fact i s anythi ng that can be proved. For exam pl e, it can be proved that Chi na has m ore peopl e than any other country i n the worl d. Thi s is a fact. Then what is an opi ni on? An opi ni on i s what som eone bel i eves i s true but has not ben proved. So an opi noi on i s not good evi dence i n a trail . For exam pl e, i t i s an opi ni on i f you say “Cats are better pets than dogs”. It m ay be true, but i t i s di fi cul t to prove. Som e people m ay not agree wi th thi s opi ni on but they al so cannot prove that they are ri ght. In a trail , a judge m ust deci de whi ch eyewi tnesses to bel i eve and whi ch not to beli eve. The judge does not consi der what each eyewitness l ooks l i ke or where that person l i ves or works. H e/She onl y cares about whether the eyewitness has gi ven true i nform ati on, whi ch m ust be facts rather than opi ni ons. Thi s ki nd of i nform ation i s cal ed evi dence. Bi g Feng to the rescue Hi s friends and famil y cal l him “Big Feng” because he is bery tal and pl ayed basketbal l as a young man. But he is al so big in a di ferent way — he fights hard to protect China’s past. His real name is Feng Jicai and he has written many novel s about life in Chi na. Several years ago, however, he put down his pen for a whi le and began to protect the cl tural reli cs i n Ti anjin, where he l ives. O nce som eon asked him why he no l onger wrote. H e repl i ed that at the mom ent he fel t protecti ng cul tural reli cs was m ore im portant. Feng l oves his hom etown. H e bel i eves that ol d thi ngs m ust be gi ven a plave next to new thins, or peopl e wi l soon fet ther great past. He does not m ake speeches to get others to hel p hi m i n hi s projects. Instead he goes out and does what he can hi m esel f. If others fol ow him , so m uch the better. One of hi s bi ggest projects was to protect the ol dest street i n Ti anji n. Al ong that street som e shops had done busi nes for seven hundred years. Al thought the ci ty governm ent rebui lt thi s street, they di d save its ol dest bui l di ng. Another project was m ore successful: he persuaded the ci ty governm ent to buy som e l and i n the centre of the city so i t coul d not be sol d for busi nesses. Thi s area i s very i m protant for the history of Ti anji n. It was here that the city was fi rst buil t duri ng the Song Dynasty. Later m any treasures were found here. To Feng, di ggi ng down i n to the earth i s l i ke readi ng page after page of a book. Each dynasty found in the earth i s l ike an interesti ng story. Not l ong ago he and other wri ters and arti sts took photos of the ol d parts of Ti anji n. The photos were put i nto a book whi ch was very popul ar. The m oney from the book hel ps hi s prjects. O nce, and ol d man asked Feng to si gn a book for him, sayi ng he woul d give i t to hi s grandson who was not yet born. Feng was gl ad to do i t he knows that he past i s not onl y for us to enjoy but al so for the chil dren of the future.
