 A civil action brought against a citizen shall be under the jurisdiction of the people's court in the place where the defendant has his domicile; If the defendant's domicile is different from his habitual residence, it shall be under the jurisdiction of the people's court in the place of his habitual residence. A civil action brought against a legal person or other organization shall be under the jurisdiction of the people's court in the place where the defendant has his domicile.
