It looks like you need a lot of extra fuel.... You can decide how much you trust the website...
FUEL REQUIREMENTS
All domestic flights must have enough fuel to:
A. Fly to the airport to which the flight was dispatched;
B. Thereafter, fly to and land at the most distant alternate airport (if an alternate is
required) for the airport to which dispatched; and
C. Thereafter, fly for 45 minutes at normal cruising fuel consumption.
Certificate holders who are authorized by CAAC can determine the fuel requirement
by means of flying from specified airport to alternate. No person may dispatch or take off an
airplane unless it has enough fuel to fly from the specified airport to and land at an alternate
airport, and thereafter fly for 45 minutes at normal cruising fuel consumption. But the fuel
quantity is not less than the requirement to fly to destination dispatched, and thereafter fly
for 2 hours at normal cruising fuel consumption.
The fuel required for a flag flight landing within the contiguous China is the same as
for domestic flights.
Nonturbine and turbo-propeller-powered airplanes flight (with an alternate available)
landing outside the contiguous China must have enough fuel to:
A. Fly to and land at the airport to which it is dispatched;
B. Thereafter, fly to and land at the most distant alternate airport specified in the
dispatch
release; and
C. Thereafter, fly for 30 minutes plus 15 percent of the total time required to fly at
normal
cruising fuel consumption to the airports specified in paragraphs I and 2 of this
section or to fly for 90 minutes at normal cruising fuel consumption, whichever is
less.
No person may dispatch a nonturbine or turbo-propeller-powered airplane to an
airport for which an alternate is not specified, unless it has enough fuel, considering wind
and forecast weather conditions, to fly to that airport and thereafter to fly for 3 hours at
normal cruising fuel consumption.
Turbojet-engine-powered air carder airplanes, other than turbo propeller, flight (with
an alternate available) landing outside the contiguous China must have fuel to:
A. Fly to the destination, then
B. Fly 10 % of the total time required to fly to the destination, then
C. Fly to and land at the most distant alternate, then
D. Fly for 30 minutes at holding speed at I 500 feet above the alternate.
No person may release a turbine-engine powered airplane (other than a
turbo-propeller airplane) to an airport for which an alternate is not specified unless it has
enough fuel, considering wind and other weather conditions expected, to fly to that airport
and thereafter to fly for at least 2 hours at normal cruising fuel consumption.
