2019年7月21日晚上，元朗有白衣人無差別恐怖襲擊市民，數百名疑有黑社會背景人士用武器襲擊市民，致大批市民受傷。
元朗區議員麥業成當日收到可能襲擊消息，並通知警方，而警方宣稱已作出部署。可是警方沒有阻止事件發生，市民被襲時亦沒有警察到場執法。721元朗恐襲被視為「警鄉黑勾結」，催化日後多場的示威抗爭，「721 唔見人」的口號因此而生。
事隔一年，大部分白衣人仍然逍遙法外，只有7人被控。網民號召今日下午1時在中環「和你Lunch」快閃，無懼《港區國安法》。
下午1時，數十人在中環置地廣場中庭共三層聚集，高舉白咭抗議，因為港府指「光復香港 時代革命」有港獨意味而被禁。並高唱《願榮光歸香港》，展示對抗爭「五大訴求 缺一不可」熱情未減。
下午1:15，數十防暴警察進入置地廣場各層，中斷集會，拉起封鎖線，查證在場市民。
On the evening of July 21, 2019, men dressed in white attacked citizens indiscriminately in Yuen Long. Hundreds suspected of having triad background attacked citizens with weapons and injured a large number of them.
Yuen Long District Councillor Mak Ip-sing received news of a possible attack that morning and informed the police, who claimed to have made deployments. However, the police did not prevent the incident from happening, and no police were present to enforce the law when the citizens were attacked. The July 21 Yuen Long terror attack was deemed a “police, rural and triad collusion”, which was the catalyst for many protests that followed, and the slogan “July 21 police missing” was born.
One year later, most of the men in white are still at large, only 7 were charged. Netizens launched the “Lunch with You” flashmob in Central today, undaunted by the passing of the Hong Kong version of National Security Law.
At 1 pm, several dozen gathered at all 3 levels of Landmark atrium in Central. They raised white placards to protest, as “Free Hong Kong, Revolution of Our Time” is deemed pro-Hong Kong Independence and banned by the government. They sang “Glory to Hong Kong”, demonstrating they are resolute in “5 Demands, Not One Less” in their protest.
At 1:15 pm, dozens of riot police entered all levels of the Landmark and interrupted the gathering. Police pulled up a blockade line and checked the identity of the citizens present.
