That's sad that many of these Indian Chinese had to leave India for Canada and other western countries due to the policies and persecution of PM Nehru's Govt. Most of them are Hakka.
The Hakka Chinese are the most entrepreneurial and hardworking people. They long faced persecution by other Han and Manchu Chinese and emigrated around the world, including India. And did great things wherever they went.
For example, Lee Kuan Yew of Singapore who built the city-state from ground up into a modern developed country was a Hakka. Thailand's former PM Thakshin and Taiwan's former PM Tsai Ing-Wen were Hakka. Some say even Deng Xiaoping of China was a Hakka.
After a certain age, your parents slowly become your children. They start to ask simple questions, repeat stories, and depend on your patience the way you once depended on theirs. Very few understand this role reversal.What looks like innocence or inconvenience is really time coming full circle. Don't correct them harshly. Don't rush them. Care for them the way they once protected you. This is not a burden. It is repayment.
