“追溯到”
用英语怎么说？

At first glance, Bia hơi served in Hanoi's Ba Dinh Sports Center seems like the same light draft beer found everywhere in Vietnam's capital. This fresh, preservative-free beer has been brewed daily since the 1960s. It is traditionally served in a sturdy, recycled glass cup known as the "cốc." While the beer is sold throughout the city, regulars at this specific sports center believe their beer is fresher and of higher quality. A regular customer in his 70s explains that their beer is served directly after brewing, maintaining its original quality. This privilege dates back to the subsidy era when state-owned shops provided special goods to officials. Although the sports center is now open to the general public, it remains a favorite spot for retired senior officials who enjoy the traditional atmosphere and affordable prices.

乍看之下，在河内巴亭体育中心供应的 Bia hơi 啤酒似乎与越南首都随处可见的淡生啤没有什么不同。这种新鲜且无防腐剂的啤酒自20世纪60年代以来每天都在酿造。传统上，它装在一个被称为“cốc”的结实再生玻璃杯中。虽然这种啤酒在全市销售，但该体育中心的常客认为他们的啤酒更佳、更新鲜。一位70多岁的常客解释说，他们的啤酒在酿造后立即供应，保留了最纯正的品质。这种特权可以追溯到国家商店向官员提供特供商品的补贴时代。虽然该体育中心现在向公众开放，但它仍然是退休高级官员最喜欢的地方。
