Narrative:
While departing on the tung lung departure, runway 7R, we received an altitude restr of 7000 ft. While leveling at 7000 ft and just after crossing over td VOR, hong kong radar advised us our heading did not appear to be in accordance with the SID. Radar assigned a new heading of 130 degrees then direct to snapa intersection. ATC advised us of the need to follow the SID in order to remain clear of possible arriving traffic. Problem: there are 2 pages to the SID and it is not really clear that the SID is to be followed from both pages. This allows pilots to understand after td VOR you may proceed direct to elato intersection. Supplemental information from acn 492523: on the SID, there is no transition mentioned, nor is there a reference to another page. If we are to adhere to additional routings, I would think there would be leaders to that/those page(south) on the particular SID itself.

Title: TRACK DEV ON THE TUNG LUNG 1 DEP FROM HONG KONG, PRC. 2 CHARTS WERE REQUIRED AND ONLY 1 WAS USED.
Narrative: WHILE DEPARTING ON THE TUNG LUNG DEP, RWY 7R, WE RECEIVED AN ALT RESTR OF 7000 FT. WHILE LEVELING AT 7000 FT AND JUST AFTER XING OVER TD VOR, HONG KONG RADAR ADVISED US OUR HDG DID NOT APPEAR TO BE IN ACCORDANCE WITH THE SID. RADAR ASSIGNED A NEW HDG OF 130 DEGS THEN DIRECT TO SNAPA INTXN. ATC ADVISED US OF THE NEED TO FOLLOW THE SID IN ORDER TO REMAIN CLR OF POSSIBLE ARRIVING TFC. PROB: THERE ARE 2 PAGES TO THE SID AND IT IS NOT REALLY CLR THAT THE SID IS TO BE FOLLOWED FROM BOTH PAGES. THIS ALLOWS PLTS TO UNDERSTAND AFTER TD VOR YOU MAY PROCEED DIRECT TO ELATO INTXN. SUPPLEMENTAL INFO FROM ACN 492523: ON THE SID, THERE IS NO TRANSITION MENTIONED, NOR IS THERE A REF TO ANOTHER PAGE. IF WE ARE TO ADHERE TO ADDITIONAL ROUTINGS, I WOULD THINK THERE WOULD BE LEADERS TO THAT/THOSE PAGE(S) ON THE PARTICULAR SID ITSELF.
