Honey from the African forest is not only a kind of natural sugar, it is also delicious. Most people, and many animals, like eating it. However, the only way for them to get that honey is to find a wild bees' nest and take the honey from it. Often, these nests are high up in trees, and it is difficult to find them. In parts of Africa, though, people and animals looking for honey have a strange and unexpected helper—a little bird called a honey guide.

The honey guide does not actually like honey, but it does like the wax in the beehives. The little bird cannot reach this wax, which is deep inside the bees' nest. So, when it finds a suitable nest, it looks for someone to help it. The honey guide gives a loud cry that attracts the attention of both passing animals and people. Once it has their attention, it flies through the forest, waiting from time to time for the curious animal or person as it leads them to the nest. When they finally arrive at the nest, the follower reaches in to get at the delicious honey as the bird patiently waits and watches. Some of the honey, and the wax, always falls to the ground, and this is when the honey guide takes its share.

Scientists do not know why the honey guide likes eating the wax, but it is very determined in its efforts to get it. The birds seem to be able to smell wax from a long distance away. They will quickly arrive whenever a beekeeper is taking honey from his beehives, and will even enter churches when beeswax candles are being lit.

There's nothing wrong with a tomato that isn't perfectly rounded or a peach with an extra dimple (浅凹) or two; they still carry the same benefits and flavors as the versions we're used to seeing in grocery stores. Farmers conventionally throw away these imperfect items, as many grocery chains won't buy them for fear that they are unsellable. However, a growing group of grocery chains are fighting to make these deserted fruits and vegetables part of consumers' buying habits.

One such business is Imperfect Produce, a start-up that delivers fresh ugly produce to consumers. Through this service, you can get up to 20 pounds of fruit and veggies for around $20 a week. This is about a 30 percent discount compared to what's currently sold in stores. Recently, the company had a major breakthrough when Whole Foods accepted their partnership and agreed to sell the misshapen (畸形的) produce.

While this movement might be a new trend here in the US, it's already gained serious momentum (势头) in Europe. In 2014, the E. U. announced the Year Against Food Waste, with French grocery chain Intermarche launching a very successful campaign called Inglorious Fruits and Vegetables and England's Waitrose selling "weather blemished" apples. In Portugal, a similar company to Imperfect Produce called Fruta Feia has also taken off.

Buying these unfortunate-looking foods should be appealing to consumers not only because of the affordability, but also because of the support it gives to farmers and the direct impact it has on decreasing food waste and the environmental pollution. It is believed that when the discarded fruits and vegetables decompose they release methane, a greenhouse gas that, when released into the gtmosphere, is about 86 times as powerful as carbon dioxide over a 20-year period. Waste is, in fact, the ugliest thing of all.

Li Jianguo, a 49-year-old teacher at the Tianjin Vocational Institute, is set to be named as one of the "2022 most beautiful teachers"-an annual public award sponsored by the Publicity Department of the Communist Party of China Central Committee and the Ministry of Education.

Li has stood out by taking the lead in the training of students in vocational skills, gaining a number of honors including being named as a national role model teacher. He has mentored(指导)seven national-level technique experts and a team of 14 technique masters. One of his students, Guo Jinpeng, who graduated from the institute in 2007, became a college teacher at the Chengdu Auto Vocational and Technical School and was named as a national role model teacher in 2019. 

Li's nomination as one of the "2022 most beautiful teachers" reflects that China is focusing on the importance of vocational education and aims to foster(培养)more leading personnel with the spirit of craftsmanship in the manufacturing industry.

At an international vocational and technical education conference in Tianjin last month, Li noted that there is no difference between vocational education and ordinary education, and vocational education is not secondary nor should it ever be treated as less than ordinary education. "Vocational education has the mission of fostering a quality workforce and technical experts for the country. The hardworking spirit is the key to building any ordinary people into leading personnel," he said.

Li joined the institute in 1993 and later founded a machinery engineering practice center, providing free training to 7,500 people a week. In 2015, he led a team of teachers to work for 40 days to repair 124 machine tools in the center. Li has devoted himself to building the country's first additive manufacturing technique and application center at the institute to satisfy the thirst for the country's human resources in 3D printing.
