Reading Time: 6 minutes Since pandemic, I have been back to China twice, last year in the spring break of school year 2022/2023, which was the 1st time I visited China since pandemic, when the PRC (People’s Republic of China) just relaxed in-bound travel in Jan 2023, and I booked ticket on Jan 29, 2023 via Expedia.com – refer
Reading Time: < 1 minute This article is also available on Medium, and blog.wenxuecity.com 航空公司 发现加航🇨🇦的loyalty member (Aeroplan)在飞机上用微信，手机短信等是免费的。不用花钱或点数买inflight WiFi：感觉又赚了一个亿[捂脸]。航空公司其实很难赚钱：成本在那里，固定成本和浮动成本等。但是另一方面愿意额外付钱的客户不多：比如说inflight WiFi, 比如说duty free product sale等等。股神巴菲特也说过类似的话：我估计他老人家在上回pandemic 那次卖了航空股以后就不会再玩航空公司的股票债券了：他老人家今年有93或94岁了。|| 我个人觉得纯从商业的角度出发，信用卡公司的商业模型business model 比航空公司好太多：她们基本上就是高速公路和谷歌的收买路钱的方法。不过在中国大陆感觉支付宝和微信支付基本上打遍天下无敌手，Visa 和万事达两大巨头基本上可以洗洗睡了。前两者的对商家来说成本比信用卡低太多。Alipay 和WeChat Pay 在香港也很拼，有不少商家也开始接受人民币的微信支付/支付宝。不过香港的payment 有点复杂：感觉基本上是八达通Octopus, 信用卡💳包括digital wallet Apple Pay, Samsung Pay, Alipay, WeChat pay等；还有出租车也就是的士🚕和地铁🚇需要的港币现钞。我用CS debit card 直接在银行的ATM机上取了些港币现钞。感觉在大陆用现钞的地方比香港少很多，基本上微信和支付宝都可以搞定。|| 离港上飞机之前有个小插曲，紧张程度有点类似于我上次工作中play as tech lead for production release：中间也出了点不大不小的问题，好在最后在超级队友的支持下，有惊无险。我感觉自己还是在这些大大小小的事情中，不断学习，提高自己[微笑] 中国好还是美国好 我被问到的一个常见的问题是：中国好还是美国好？我觉得各有千秋吧。比如说火车：美国的火车客运还停留在中国的绿皮车年代，中国的高铁确实挺牛。Amtrak 没有固定位置: no assigned seat 💺 on
