"曹晖，我的儿子，论水平论资历他都不如你们，但是他有一个比你们强，他是我曹德旺的儿子，"这是 多年前曹德旺在一档节目中提起自己儿子时亲口说的话。曹德旺把1700亿的福耀玻璃交给儿子曹晖，理 由很直接："他是我儿子"。 ...

然而10月18日凌晨5点，你本来做好悲壮准备的母亲开始感受到规律的疼痛，在疼痛持续半小时后，我们意识到情况不同以往，晚些洗澡时脱落的宫颈粘 膜更是印证了这个判断。吃完了早饭（你妈妈很后悔只吃了一根芝士香肠），我们和你的奶奶和姥姥便打车前往医院，幸运地拿下最后一个套间，在检查 室签署海量的文件。 小松花： 见信好。 此时此刻，你的生物学父亲（并不是每个男人都有我这样十足的信心，这份信心源自对你伟大母亲的信任），也就是我，正在香港大学深圳医院昏暗的待 产房里，听着中央空调和血压仪收缩的声音，窝在充满抓痕的旧沙发上，用iPad敲下这些文字，为你出生的过程做些记录，也让未来我们一起回忆这段甜 蜜时光时，能提升一点颗粒度。 套用当下最流行的MBTI十六型人格理论，你是一个很J的孩子。 你在妈妈肚子里待满40周的预产期是10月18日，由于你的很多姨姨都在满37周发动，所以早在国庆假期前，你同样很J的母亲就做好了致敬前辈的准备， 敦促我收拾好了待产包和住院的行李，还威逼我把电脑搬出你的房间。于是我丧失了独自熬夜玩《空洞骑士：丝之歌》的机会（愿你也能玩到这么好的游 戏）。只能说我因此增加的寿命，背后也有你对我的一片孝心。 但 ...

当地时间10月16日，特朗普在个人社交媒体上证实，与俄罗斯总统普京进行长达两个半小时的电话会谈。 会谈是俄方主动发起的，有媒体猜测是想抢在泽连斯基赴美之前先给特朗普"下药"。 通话期间，特朗普提议于未来两周左右在匈牙利首都布达佩斯举行高峰会，以寻求战争结束，具体日期取决于先前两国外长的会晤结果。 不同于泽连斯基以及欧洲政治人物，普京可以在一些敏感议题上尽情挑特朗普喜欢的说，诸如：2020年大选是你赢了，拜登偷走了选举胜利； 如果是你在，这场战争根本就不会发生；你是今年和平奖当仁不让的得主，那些左派人士对你有偏见…… 正因如此，乌克兰和欧洲国家其实很不希望二人接触。 上次阿拉斯加会晤结束后，欧洲派出了包括英国、法国、德国、意大利领导人，欧盟委员会主席冯德莱恩、北约秘书长吕特和芬兰总统斯塔布 在内的强大阵容第一时间赴白宫磋商，好不容易才把特朗普给"拉"回来。 而就在10月16日的通话后，特朗普立场果然又发生了转变。 次日与泽连斯基会谈时，他明确拒绝向乌克兰提供"战斧"导弹，美媒称白宫会谈"气氛紧张"，泽连斯基本人则表示"对话尖锐"。 根据媒体放出的消息，普京在谈话中做了一些让步——在继续坚持要求乌军退出顿涅茨克州 ...
