什么值得买上面找个文章看一下好了
首先，既然买净水器了，肯定买 RO 膜的
选择上，非 DIY 的话，现在京造（ 1000 左右）、美的（ 2000 以下）、小米（ 1000 左右）几个牌子性价比比较高，后续滤芯价格比 DIY 的高
也可以自己 DIY 或者买 DIY 好的，用通用滤芯

TT 拿高 base 升到 2-1 跳槽，然后外面级别上去了，过几年再跳回去

合同改签到符合条件的公司（如果是阿里，很容易），然后同步把积分办起来，先解决幼儿园的问题。顺利的话，一年后就可以落户了（落户办理在几个月）。不影响后续小学。

三墩北、良渚看看

看到有一个数据岗，英文要求如何？

@WildDonkey 快退休再交可能就要缴满 20 年了
