    Folding(可折叠的) bikes work well for people who ride the train. Just fold the bike and take it with you. You can do the same on an airplane. A folding bike can be packed in a suitcase.

Rongbao is happy to welcome friends from all over the world（全世界）. I think Rongbao looks cool and strong. Look! Whose Rongbao is that on the desk? Oh, it's not mine. It's Amy's. She buys it in Chengdu. I want to buy one, too.
