In 2021, the sea burial activities in Qingdao were held in multiple batches, usually arranged in spring and autumn. The specific registration time was announced by the relevant departments.
Normally, for collective public welfare sea burials, the processing would be completed within one year from the date of registration, while for collective high end sea burials, it would be completed within half a year. To register for sea burials in 2021, applicants needed to go to the Sea Burial Business Hall of the Qingdao Funeral Service Center at No. 178, Chongqing South Road. The staff would notify the applicants of the sea burial time and relevant handling matters 2 3 days in advance according to the queuing situation and weather conditions.
Some regions organized sea burial activities jointly with Qingdao. For example, the autumn sea burial service in Weifang in 2021 was planned to be held in Qingdao in late September (the specific time was to be determined according to the epidemic prevention and control situation), and its registration deadline was September 20.
In addition, some cities like Jinan organized sea burial activities in Qingdao regularly. Jinan's second funeral home organized sea burial activities in Qingdao from April to October each year under the arrangement of the Civil Affairs Bureau.
If you intended to participate in the sea burial activities in Qingdao in 2021, it was advisable to pay close attention to the announcements from local civil affairs departments or relevant official channels to ensure that you did not miss the registration time.
