It was such a painful experience to watch the whole period of my mom's final hours.   The next day after my mom said she saw heaven opens, the doctor told us that my mom might not have more than 3 days left since she started to have failure in her body and can't not retain oxegen, the doctor told us to think about whether we want to use breathing tube on my mom.  That afternoon my brother thought my mom was all right and went to meet a friend, got a bad traffic and didn't get in till the very last minute for visiting. My mom kept asking about him. We had to leave before discussing what we want to do about the breathing tube, although both me and my sister discussed and wanted my mom to have natural death.   In the evening, around 8:40pm we got a phone call from hospital telling us my mom was in danger. When we got hospital, the doctor told us my mom was choking on her mucus and couldn't breathe, they used breathing tube　（ｗｉｔｈｏｕｔ　ｏｕｒ　ｃｏｎｓｅｎｔ　ｏｖｅｒ　ｔｈｅ　ｐｈｏｎｅ　ｏｒ　ｉｎ　ｐａｐｅｒ　ｓｉｎｃｅ　ｗｅ　ｈａｖｅ　ｔｏ　ｓｉｇｎ　ｉｔ　ｆｉｒｓｔ） after trying to revive her just by human efforts. My mom's brain was out of oxegen for 15 minutes and was brain dead, but in China there is no concept of  Euthanasia (安乐死), she has to stay like that till her heart stops beating.　Ｔｈｅ　ｄｏｃｔｏｒ　ｓａｉｄ　ｉｔ　ｍｉｇｈｔ　ｂｅ　ａ　ｆｅｗ　ｄａｙｓ　ｏｒ　ａ　ｆｅｗ　ｗｅｅｋｓ　ｂｅｆｏｒｅ　ｈｅｒ　ｆｉｎａｌ　ｔｉｍｅ，　ｓｏ　ｗｅ　ｗｅｎｔ　ｈｏｍｅ．
