We arrived Warsaw on Sept. 11th 2018, and visited Belos-PLP Poland and attend the electrical fair there. After the fair, we went to Czech Republic by train on Sept. 14th, 2018, then visit our partner there, our client brought us walk around in Czech and enjoyed the time there.
After the visiting in Prague, we went to Romania on Sept 19th 2018. We have a had a wonderful journey there. They were so hospitable, we spent the mid-autumn festival in a real chinese restaurant, the taste and feeling just like at home. 
Its really a nice trip, we met VIP partners and have had a gread site seeing there.
