I got the notice of arbitration hearing, but I didn't understand the meaning.

The notice of arbitration hearing is also a notice issued by the arbitration commission, depending on the specific content of the notice.

The arbitration hearing time shall be decided by the arbitration tribunal and the secretariat/office of the Arbitration Commission, and the parties shall be notified 30 days in advance, so that the parties have sufficient time to arrange their work. However, the notice of the date of hearing after the first hearing is not limited by 30 days. If the parties have justified reasons, they may request the secretariat of the Arbitration Commission to postpone the hearing 12 days before the hearing, and the arbitration tribunal shall decide whether to postpone the hearing. The purpose of 12 days in advance is to leave room for other parties and arbitrators in the schedule.

Article 9 of the Arbitration Law of People's Republic of China (PRC) implements the system of final arbitration. After the award is made, if the parties apply for arbitration or bring a lawsuit to the people's court on the same dispute, the arbitration commission or the people's court will not accept it. If the award is revoked or not executed by the people's court according to law, the parties may apply for arbitration according to the arbitration agreement reached by both parties, or bring a lawsuit to the people's court. Article 10 Arbitration commissions may be established in municipalities directly under the Central Government and cities where the people's governments of provinces and autonomous regions are located, or in other cities divided into districts according to needs, and shall not be established by administrative divisions. The arbitration commission stipulated in the preceding paragraph shall be established by the Municipal People's Government and organized by relevant departments and chambers of commerce. The establishment of an arbitration commission shall be registered by the judicial administrative departments of provinces, autonomous regions and municipalities directly under the Central Government. Article 25 After accepting an application for arbitration, the Arbitration Commission shall serve the arbitration rules and the roster of arbitrators to the applicant within the time limit stipulated in the arbitration rules, and serve a copy of the arbitration application, the arbitration rules and the roster of arbitrators to the respondent. After receiving a copy of the application for arbitration, the respondent shall submit a statement of defense to the arbitration commission within the time limit stipulated in the arbitration rules. After receiving the written defense, the Arbitration Commission shall deliver a copy of the written defense to the applicant within the time limit stipulated in the arbitration rules. The failure of the respondent to submit the written defense shall not affect the arbitration proceedings.
