On the second anniversary of the Yuen Long attack, the police strengthened their defenses in the Yuen Long area. Among them, more than 100 police officers patrolled and deployed guards on the overpass and grounds of the MTR Yuen Long station. They were wearing puncture vests. Police officers also stepped up patrols and intercepted citizens in the Yuen Long city centre. At 6 pm, Tin Shui Wai Connection, Confederation of Trade Unions and Wong Yat-chin, the convener of Student Politicism, set up a street booths at the ground public transport interchange at Yuen Long station. Through broadcasting and handing out leaflets, we hope that the public will 'not forget the 721 incident'. Police officers registered their ID card information, and repeatedly asked citizens at the scene not to stay on the grounds that they might violate the gathering restriction order. The 3 people stayed for about 1 hour and then left. In addition, members of the Hong Kong Hotel Union set up a street station at the same location at about 2 pm. They were intercepted by the police during the distribution of the epidemic prevention leaflet with the word 721 written on it. The police officer claimed that the cartoon pattern on the leaflet was related to the "black storm". It is also warned that if the distribution continues, the staff of the National Security Department will be notified to investigate, and finally they will leave.
