Actually they would have had about 40,000kg's trip fuel for that routing last night which should have took 5 1/4 to 5 and 1/2 hours. Depending on Alternates - which are TIANJIN (ZBTJ) and Zhengding (ZBSJ) for Beijing your looking at another 10-15,000kgs in additional fuel after ALTN, FINAL, APU, TAXI, CONT and any Additional fuel the flight crew chose.
Total's of around about 50-60,000kgs are correct.
Your post was not helpful in the slightest, mine was responding to someone asking how much fuel they had on-board so based upon EU Operations you are looking at about 7 hours or so for a 5 and bit hours flight. So thank you for your kind "I am 21 year old and no nothing gesture" - it really helps this thread.
