The embalmed body of Ho Chi Minh is preserved in the cooled, central hall of the mausoleum, which is protected by a military honour guard. The body lies in a glass case with dim lights. The mausoleum is closed occasionally while work is done to restore and preserve the body but is normally open to the public every morning. Lines of visitors, including visiting foreign dignitaries, pay their respects at the mausoleum every day. Rules regarding dress and behavior are strictly enforced by staff and guards. Legs must be covered (no shorts or miniskirts). Visitors must be silent and walk in two lines. Hands must not be in pockets, nor arms crossed. Smoking, drinking, eating, photography and video taping are also not permitted anywhere inside the mausoleum.
