Madolline is from Australia. Over the past few years, she has traveled to many cities in her country and in the US. And she has spent very little on these trips. How did she manage to do this?

Well, Madolline grew up with cats and has always been a “big cat fan.” In 2017, she discovered a pet sitting website. She started looking on it for jobs in different cities. “As a pet sitter, you help your customers take care of their pets,” she explains. “In return, you get to live in their homes for free.”

Madolline spends about 30 minutes a day caring for her customers’ cats. “I’m usually asked to feed the cats twice a day. I also need to change their water and clean their litter boxes every day or two,” she said. She sends her customers two or three photos or videos of their pets each day. This is to tell them the latest condition of their pets.

Madolline will also do other simple tasks for her customers if they need. These tasks include collecting mail and taking out the rubbish. In the rest of the time, she is free. She can tour the city she is in.

Madolline has always shared her journeys online. Her next trip will be in Canada. And she is looking for places to stay there!

William is British, but he is an expert (专家) on China’s Great Wall. He married a Chinese woman and lived in Beijing. His two sons, James and Thomas, are 28 and 21 years old. They have shared their father’s interest in the Great Wall since they were children.

In 2016, the brothers made some videos about the Great Wall. Some of them were shown on the BBC and some Chinese websites. Last year, they decided to take it a step further to experience the Great Wall by walking along it.

On July 15 last year, the brothers set out from Jiayu Pass in Gansu Province. They walked about 30 kilometres a day. They sometimes spent the night in hotels. Other times, they camped in the wild.

The two traveled along the main part of the Great Wall from west to east. After 131 days, they finally reached the Shanhai Pass in Hebei Province. Their journey covered more than 3,000 kilometers.

William is very proud of his sons. “The Great Wall is more complicated (复杂的) than we had thought,” said the brothers. “This trip has given us a better understanding of it!”

Are you looking for a good volunteer (志愿者) activity? Get outdoors and go gleaning (拾遗)!

What is gleaning? Well, let’s begin with the problem of food waste on farms. Some farm products are good but look imperfect. Farmers don’t usually try to sell them in markets. Many of them are left to rot in the fields. This is a great waste. And gleaning is about reducing this waste—by collecting the products.

These days, many volunteer groups go out gleaning in order to provide those in need with fresh, healthy food.

Holly’s group is one of them. Her volunteers collect about 300 boxes of food each week. Once, a local fruit farmer called Holly to ask for gleaning services. He had a large field with more than 700 fruit trees. A member of Holly’s group created an online map of the trees. With the help of the map, the volunteers quickly collected the fruit from the trees.

Besides this, Holly’s volunteers have also picked other vegetables from local farms. The food has been sent to food banks and community kitchens in her area.

Gleaning helps solve the problems of farm waste and food shortages (短缺). And gleaners also find the work brings them a sense of achievement. “We can get outside and do something good for the world,” said Holly. “I feel pleased whenever I go gleaning!”

Traditionally, tourists like to make use of every second of the day. They rush from one place to another. When they finally get to their hotel rooms at night, they often find it hard to sleep though they are tired. Most city hotels may be in the city centre. But it usually also means noisy traffic and bright streetlights. As a result, many people simply do not sleep well in these hotels.

To solve this problem, many hotels are offering special sleep suites (套间). These suites are made to provide quietness and darkness. Some hotels are even buying smart beds for these suites. They can not only help users relax their bodies but also record their sleep.

In addition, many hotels use other ways to help people sleep better. Some provide a menu of relaxing teas. Others offer services such as massages (按摩) after meals.

Some sleep scientists believe these sleep suites are a result of the pandemic (流行病) in the past three years. In those days, many people had trouble sleeping because of illness and worries. So after the pandemic, hotels have paid more attention to sleep problems.

Sleep suites are a huge step forward for the travel industry. Only when we are well rested while traveling can we feel more relaxed after we return home!
