<to> = "到" | "去" | "飞";

<city> = "北京"       {nf.I($@)}
       | "天津"       {nf.I($@)}

       | "重庆"       {nf.I($@)}
       | `.(?:城|都)` {nf.I($@)}
       ;

<city_ext> = <city>            {nf.I($1)}
           | (any{1,1}) <city> {nf.I($2)}
           ;

<cities> = "直辖市:" (list<city_ext>) {nf.I($@)};
