He has continued to experiment and promote novel products, and has even attempted to sell tangyuan soup with mangoes in winter.
Tangyuans are glutinous rice balls that are cooked and served in boiling water that are traditionally eaten during the Lantern Festival.
Chang said the experiment did not start well, with several customers complaining about the taste and edibility of the product.
However, after two years of continuous trials, Chang managed to make the dish more appealing to his customers.
“It has since become a best-seller during the winter season,” Chang said, adding that customers were always his best teachers as they offered the most direct opinions on the taste of the products.
Chang also said that he plans to research how to make mango tea and cosmetic products using mangoes.
Commenting on the difference between his current business and his previous career, Chang said that while his previous salary was considerable, it also came with a lot of responsibility.
“I saw a lot of things during my 14 years at the company, including the deaths and ailments of patients in hospitals,” Chang said.
“You only live once, and you don’t get a restart button, so make the best of your dreams as you can,” Chang added.
Chang also wished to encourage the younger generation not to be afraid if they wanted to start their own business or do something that would help them realize their dream.
If one holds to a unique path and perseveres with continued innovation, success will not be a stranger, Chang said.
