Dear Peter,

China's National Treasure

    Pandas are in danger of extinction at present, with only 1,900 remaining in the world. The scientific name of the giant panda is actually called the cat bear, the number of which is very scarce. It is one of the most precious animals in the world and belongs to the protected animals at the national level. Its body color is black and white. Giant pandas are unique to China, very cute. The existing major habitats are in the surrounding mountainous areas such as Sichuan and Shanxi in China. The giant panda has a very powerful function: digesting bamboo. We all know that bamboo is mainly cellulose (纤维素), and most animals can't digest it except giant pandas. The giant panda's hometown is in the mountains southwest of China, green bamboos and springs everywhere. Therefore, the giant panda's main food consists of bamboo and spring water.

    Giant pandas are often referred to as living fossils. Hundreds of thousands of years ago, it was the peak period of giant pandas. This is of great scientific value for studying and protecting biodiversity and environmental changes on the earth. Long, long ago, the climate of the earth became colder and colder, many ice cubes formed on the earth; plants could not grow, and many animals were frozen or starved to death. The giant panda alone survived in the deep valleys of the mountains and became a treasure of the animal world. The giant panda still retains the characteristics of ancient animals. Therefore, the giant panda is not only popular with adults and children in terms of appearance, but also becomes a living fossil for biologists to study ancient creatures.

    The status of giant pandas has been politicized. Giant pandas can be seen in almost all the major countries in the world. The giant panda has become a witness of friendship between China and foreign countries. For decades, wherever the giant panda goes, a panda whirlwind will blow. With its charmed figure and natural cuteness, the Chinese giant panda attracts numerous fans around the world, and at the same time plays the role of friendship ambassador in China's foreign exchanges, becoming one of the most famous symbols in China.

    Sadness and depression?

    Sadness is normal human emotion that everyone experiences at some time. A number of events can leave people feeling sad or unhappy, such as the loss or absence of a loved one, divorce, loss of job or income, financial trouble, issues at home, or social anxiety.

    Failing an exam, not getting a job, or other disappointing events can also trigger sadness.

    However, a person who is sad can usually find some relief from crying, venting, or talking out frustrations. This is because sadness is more likely to be linked to a specific trigger.

    Sadness usually passes with time. If it does not pass, or if the person become unable to function normally, this could be a sign of depression. If symptoms worsen or last longer than 2 weeks, the person should talk to their doctor.

    Depression is a mental disorder that affects every part of a person's feelings and perception. It affects behaviors and attitudes and can affect people of any gender or age.

    In 2015 around 16.1 million people aged 18 years or above in the U. S. had experienced at least one major depressive episode in the last year. This represented 6.7 percent of all American adults. Symptoms include feelings of discouragement, sadness, hopelessness, a lack of motivation, and a loss of interest in activities that are normally enjoyable. In severe cases, the person may think about or attempt suicide.

    The person may no longer feel like spending time with family or friends. They may stop pursuing their hobbies and feel unable to go to work or school.

    Daily habits may change unexpectedly and without reason. A person with depression may find it difficult to continue doing the things they normally enjoy.

    If these feelings of doubt last more than 2 weeks, a health-care professional may diagnose the person with major depressive disorder (MDD).

    Unlike sadness, depression can leave a person struggling to express their feelings. If the person tries to release the stress, the overpowering feelings and negative thoughts can prevent them from building themselves up again.
