If the subway is extended to Luoyang Beijiao Airport, Long Distance Railway Station, High Speed Railway Station, Airport, and City Centre will be connected by metro.
Though I don't know where the subway is extended in the south, it will be convenient for tourists when it is extended to Longmen Grottoes, the World Heritage.
