The staff told him travellers from other countries had a problem with a Chinese visitor, and there were fears he could be carrying the coronavirus – despite Du pointing out airport authorities had screened him and cleared him to enter India.

“Some people did it without realising it,” Du said. “Every time I faced such a situation, I pointed out their mistakes and left in search of a safe place.”

Deciding to leave Mumbai, he set out for Goa, thinking it would be friendly to foreigners. On his way there, he stopped in Dapoli, a small town along India’s west coast. By that time, India had around 100 confirmed cases and the world had more than 90,000.

Du met more rejection in his quest for accommodation. An experienced traveller, he had come prepared with a tent and essentials for sleeping while on the road, and set up camp close to a temple. The local priest, however, had a problem with a non-Hindu taking shelter nearby, and advised Du not to venture into the main temple area.

The more he travelled, and the more cases rose, the worse Du was treated. People even started calling him “coronavirus”.

“It was a racial slur. Only when I called it wrong and warned them did they stop,” he said, adding that this was the first time he had experienced this form of discrimination in a decade of travelling outside China.

Du also came to realise that his countrymen around the world were facing similar problems, with reports of a Chinese woman in San Francisco having been spat on, yelled at and attacked while going to a gym, while a Singaporean student of Chinese ethnicity was beaten up in London.

On March 16, he moved from Goa to Karnataka and was screened at the state border. A budget hotel that had accepted him as a guest later asked him to check out after realising he was Chinese.

This time, however, Du lost his cool. He was adamant he would fight back and resist the bid to evict him. “When I refused to leave, they called the police and their attitude was no different. I stood my ground and they agreed to get me tested for Covid-19.”

The police took him to a nearby district hospital at midnight, where he was tested and given a medical certificate stating that he did not have Covid-19.

The next day, he had no choice but to set up his tent at a gas station. He even had to use his martial arts skills to ward off a young man who tried to mess with him at night.

Du has since to found a place to stay in Bangalore, taking shelter at the home of a Chinese national who is renting a house in the city.

He has been stuck there since March 19, under the national lockdown, and now wonders when he will be able to travel back to China as flights have increased five to eight times in price.

“I was always welcomed as a foreign guest in different countries,” Du said. “But this time, the pandemic has changed the minds of people for worse – not just in India but across the world.”
