CAN I BRING 2 LUGGAGE2 INTO CABLE CAR AT CHUNG TUNG GO TO LANTAO ISLAND

According to the rule, one passenger can only take one piece of luggage on the MTR of Hk. Why not store your luggage at Tung Chung Station or Citygate Outlets near to the Station? It is very inconvenient to take the luggage along with you to visit the lantau Island.
