From the link below, click "Petition Official" underneath his picture on the left. Then click on "Permanent Representative of the People's Republic of China to the United Nations ," also on the left.
In your email to the Chinese Ambassador to the United Nations please be brief and respectfully request Lacheng Ren's release. Do not mention Voice of the Martyrs, Prisoner Alert or Engage Daily. I suggest you also ask the government of China to respect Article 18 of the United Nations Universal Declaration of Human Rights, which states the following:
"Everyone has the right to freedom of thought, conscience and religion; this right includes freedom to change his religion or belief, and freedom, either alone or in community with others and in public or private, to manifest his religion or belief in teaching, practice, worship and observance."
