Today, I met two things which confused me a lot.

1.

This morning, my classmate told me that he would go to department at 12:00pm, I said” what? Are you crazy”(who would go there at midnight especially in the summer time). After the confusion, I got the answer from Wikipedia.com, and found that I had a wrong concept about 12am and 12pm.

“The 12-hour clock is a timekeeping convention in which the 24 hours of the day are divided into two periods called ante meridiem (a.m., Latin for "before midday") and post meridiem (p.m., Latin for "after midday"). Each period consists of 12 hours numbered 12 (acting as a zero), 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11. The a.m. period runs from midnight (inclusive) to just before noon (exclusive), while the p.m. period runs from noon (inclusive) to just before midnight.” So 12:** in the noon is pm.

There is another website http://longtailworld.blogspot.com/2006/04/japan1212am-is-noon-in-japan.html showing that 12am is noon in Japan, so it seems that the 12-hour clock has the different definition in Japan and maybe China.

  This afternoon, I read a book in library and found that below a picture of “Mount Everest”, it shows “Kala Patthar, Nepal”. Then I asked my Indonesian, Malaysian and Korean friends, they all told me that it of course belong to Nepal，China is too ambitious. But later I asked the friends from China and Taiwan, their answer is “definitely, absolutely and surely China”. Though I know that Nepal has the south slope and China owns the north part, every Chinese is educated that the highest point on earth lies in China (Tibet). That’s really interesting and I look up the Wikipedia, “Mount Everest is the highest mountain on Earth, measured by the height of its summit above sea level. Its summit ridge marks the border between Nepal and China.” So it belongs to the both countries, or China and Nepal shares it, it belongs to no country. BTW, in 2002, the Chinese People's Daily newspaper published an article attacking the continued use of the English name for the mountain in the Western world, insisting that it should be referred to by its Tibetan name “Chomolungma”.
