Some students from Australia went on a school trip to Qiqihar．They have been here for a week．Here is part of their chat history on WeChat．

20：00 John：Hi，everybody! Anything to share today？ 20：03 Nancy：Yes，I went to a restaurant to eat Qiqihar BBQ this evening． It was really delicious．When I finished the meal and went out of the restaurant，the waiter came out with a purse in his hand．And he told me that I had left my purse on the table． 20：04 Mike：Really？ So kind!

20：06 Linda： @Nancy You are so careless! The barbecue was so delicious that you forgot your purse． 20：10 Paul ：I went to Longsha Park．When I came out of the park，I couldn't find the way to my hotel，I asked a man who was walking by me．He took me to the bus stop and told me to take No．101 bus．I wanted to give him a hug to show thanks，but he just said godbye and walked away．Twenty minutes later，I came back to the hotel．

20：13 Linda： @ Paul It seems that Chincse people don't usually hug． 20：15 Paul：I guess so．It's really unforgettable! 20：19 John：I agree．The Chinese people I have met these days are so friendly，polite and helpful．We will enjoy the rest of our trip for sure．
