Wong Chi Kei has been adhering to the traditional noodle making method for 70 years. In recent years, it has been determined to improve the noodle making method. In terms of material selection and steaming fried process, scientific analysis has been made. Special attention has been paid to the selection and regular replacement of pure rapeseed oil, for maintaining the oily incense and removing impurities. A specially designed centrifuge is used for de-oiling the noodles, so that each noodle is not oily or greasy.

In order to make it easier for customers to buy noodles, serving them as gifts, or give gifts, the gift box "E-Fu Noodles" is specially launched, and it comes with a fragrant soup for easy cooking.
