today , i used my Eurailpass from Watford Juction to Euston ,then  went  to Victoria Station(Victiora line-the blue line)by underground ,after that i changed to the Distrist Line -the green line to South Kensington Station ,there is the Air China London Office ,i got my airplane ticket .

    then , i was back to the South Kensington Station to Victoria Station ,there is the Victoria&Albert Museum and Natural History Museum, I visited the two museums .

    the Eurailpass is very useful , valid 15 days within 2 months , i don't have to pay for the rail.

     and the 1 day travel card for the underground is also cheaper , just 5.1 pounds.Yesterday but before one, i did not know and did not  buy the ticket , so it was cost my lot of money ,just 4 pounds for three stations.

  My friend Sunny and her husband gave me lots of help , and let me save more money . It is lucky  for a stranger to have a nice friend in other countries.

   now it is london time PM22:10.
