            <p>2018 年，我们动手做第一版赛程表。要解决的问题很具体：一个赛季几十轮，比赛散在好几个地方，想看某支球队接下来的安排，得来回翻好几个页面，还常常对不上。</p>
            <p>先把能收拢的场次收拢，按日期排成一条连续的线，再把比分和赛后信息补进去。表做长以后发现，真正被反复用起来的是那些“回头能查”的部分——赛季初的对手、三个月前的主客场、某轮意外丢分前后的阵容变化。</p>
            <p>于是这件事有了明确方向：把每一场比赛都留在可以回头查阅的位置，让它过一段时间再打开，依然对得上、看得懂。足球联赛与杯赛是这条线的起点，篮球赛事的赛程、比分与战报后来也循着同一套思路整理。</p>
