Please do not keep your opponent waiting for tooooooooooooooo loooooooooooooooooooong. \n\n🍭Tips： \n1️⃣Disqualification will occur if a player loses by timeout. \n2️⃣If disqualified by the tournament director, all outstanding games will be forfeited, which will affect the player’s ranking. \n\n🍭The following rules must be obeyed to guarantee a respectful game: \n1️⃣No pauses are allowed. \n2️⃣No vacation mode is permitted. （If a player is on vacation, they and their opponent can still make a move, but time will be suspended. Soooooooooooo, vacation mode is absolutely NOT allowed.） \n3️⃣Any player who is on vacation or has paused the game will be disqualified without further notice or reminder. \n4️⃣If you find that a player pauses the game or enters vacation mode, please send a message to the tournament director. \n\nLet us strive to be respectful players. \nWe wish everyone a pleasant game and hope to gain something from our opponents. ：）",
