1 . Who're happier, men or women?Research shows it's a complex question and that asking whether males or females are happier isn't really that helpful, because basically, happiness is different for women and men.

Women's happiness has been declining for the past 30 years, according to recent statistics.And research shows that women are twice as likely to experience depression compared with men.Gender（性别） differences in depression are well confirmed and studies have found that biological, psychological and social factors contribute to the difference.

Early studies on gender and happiness found men and women were socialized to express different feelings.Women are more likely to express happiness, warmth and fear, which help with social bonding and appear more consistent with the traditional role as a primary caregiver, while men display more anger, pride and disrespect, which are more consistent with a protector and provider role.

Recent research suggests that these differences are not just socially, but also genetically related.Studies have looked into these findings further and discovered that females use more areas of the brain containing mirror neurons（镜像神经元）than males when they process feelings.Mirror neurons allow us to experience the world from other people's view, to understand their actions and intentions.This may explain why women can experience deeper sadness.Women tend to experience more negative feelings, such as more guilt, shame and to a lesser degree, embarrassment.

Psychologically it seems men and women differ in the way they process and express feelings.With the exception of anger, women experience feelings more strongly and share their feelings more openly with others.Studies have found in particular that women express more appreciation﹣which has been linked to greater happiness.This supports the theory that women's happiness is more dependent on relationships than men's.

2 . If documentary A Bite of China presented a feast for the eyes with its appetizing images of cuisines from around the country, Aerial China, a new series that was put on CCTV on Jan. 28, offers another visual treat with its footage (镜头) of the breathtaking beauty of the country's natural landscapes.

The series has 34 episodes, each featuring a different place. The first season's episodes feature scenery from Heilongjiang, Hainan, Xinjiang, Shaanxi, Shanghai and Jiangxi. According to Beijing Daily , it took one year to film the first season, with crew using 16 helicopters and 57 drones. The total distance they covered was about 150,000 kilometers - enough to circle the earth four times.

Their efforts have paid off, however. Aerial China currently has a score of 9.4 points out of 10 on douban. com, an influential rating and review website. The majority of viewers are impressed by the amazing view of nature the show presents. From the gleaming blue of the South China Sea to the vast grassland in Xinjiang, from centuries-old city walls in Shaanxi to busy ski resorts in Heilongjiang, "every frame of this show would make a desktop wall paper," commented Beijing Daily.

But amazing views are not the only thing Aerial China wants to show to the audience. " Every footage conveys the love of our motherland," chief director Yu Le said in an interview with CCTV. “The more you know about the place where we live, the more you feel obliged to protect it. " Yu also hopes that it can bring viewers some food for thought. "It allows audiences to see the world from above with brand new perspectives. It may occur to the audience that human beings are very tiny creatures in the universe and our life is very fleeting (短暂),so we should not dwell on the worries and losses. Just think outside the routine - you'll find an enriched life."
