After hearing that Iwao Tsuyoshi, his Japanese friend, would be visiting China, Yang Haihui, 35, booked some time off work.

"I will take him to the Forbidden City," Yang, who works for Japanese semiconductor manufacturer Renesas Electronics, said.

Back in 2002, Yang was sent to Japan for training, and Iwao was his supervisor. "He took me out in his spare time and showed me around," Yang recalled. Before he left, Iwao gave his Chinese colleague gifts.

Yang grew up listening to his grandfather's stories about his time as a soldier during China's War against Japanese Aggression. This colored his opinion of the country.

"Had I been told that Renesas was a Japanese company, I might not have accepted the job," he admitted. Gradually, however, he discovered that the Japanese people were not as he had imagined. "I have visited Japan more than ten times," he said. "I found the people to be mostly polite, friendly and diligent."

Love thy neighbor

China and Japan, although sharing many similarities, have a fractious relationship. Confucianism and Buddhism travelled to Japan from China, and even the characters used in Japanese are derived from the Chinese script.

Although these shared cultural characteristics have led to many Chinese having an affinity toward their eastern neighbor, the eight-year Sino-Japanese war has left a scar in the hearts of Chinese.

Ma Jiangang's uncle died fighting the Japanese Imperialist Army in the 1940s. Ma, 58, however, does not hate Japan because of this.

On the contrary, he has great memories of watching the Japanese movies and TV dramas of the 1980s, the honeymoon period between China and Japan following the normalization of diplomatic relations in 1972.

He also liked Japanese electronic appliances. "Everyone wanted a Japanese color television," he recalled. His first TV was Hitachi.

In the 1990s, however, Ma's feelings changed due to the rise of the Diaoyu Islands dispute. His daughter Huixin went through a similar change.

"I hate their leaders' visiting the Yasukuni Shrine [where war criminals are worshipped] and the denial of the Nanjing Massacre," said the 34-year-old civil servant.

A joint poll by "China Daily" and the Japanese non-profit think tank Genron NPO last year showed that 86.8 percent of the Chinese viewed Japan unfavorably, while 93 percent of Japanese had a negative impression of China, the worst since 2005.

Two sides of the same coin

At the same time, however, the two countries seem to be inseparable.

China is Japan's largest trading partner. In 2014, China provided 22.3 percent of Japan's imports. More than 23,500 Japanese enterprises have invested in China.

However hard she tried, it was not easy for Ma Huixin to eliminate all the Japanese elements from her life. Her son liked Japanese animations. Her family recently watched the movie "Doraemon: Stand by Me". The blue cat-like robot was part of the mother's childhood memories, too.

Yang Haihui said that at least one of every 10 automobiles that roll off production lines in China used chips produced by his company.

Perhaps Nanjing in Jiangsu Province, east China, is a place where anti-Japan sentiment is highest. The Rape of Nanking massacre in the winter of 1937 left at least 300,000 people dead at the hands of the Japanese. The death toll has never been officially recognized by Japan.

Taxi driver Wu Qifeng in Nanjing has a rule: Never carry Japanese. Once he discovered that two of his three passengers were Japanese, he stopped the cab immediately. "I ordered them to get out," he said. "In Nanjing, I am not the only driver to do so."

In the shopping malls, however, Japanese cosmetics still line the shelves, and books by Japanese authors are also available. "There are always people asking me 'why are there Japanese cars on the roads of Nanjing',"Wu said. He felt ashamed.

The situation was no different in Japan.

Xinhua interviewed three Japanese: A 41-year-old civil servant, a 27-year-old lawyer and a 52-year-old manager. They expressed a preference for Chinese cuisine, trust in traditional Chinese medicine and good impressions of clothes and electrical appliances made in China.

"But if I had the choice, I would only eat food made in Japan, because I always see reports of bad food quality in China," said the manager.
