During the repair process, he studies the original makers' craftsmanship and imitates their techniques. He believes that repairing birdcages is an opportunity to learn from other craftsmen and preserve the beauty of the original design.

The craft of birdcage making in Hong Kong has been recognized as a traditional handicraft and listed as an intangible cultural heritage in 2014. Despite the decline in popularity, exquisite craftsmanship continues to attract young people to learn it.

Chan has taken on eight apprentices from various professions, including design, finance, and dance. They come to his shop regularly to learn the techniques of birdcage making, and he encourages them to observe the process first to ensure they have the patience and perseverance required for the craft.

For the apprentices, birdcage making is not only about overcoming technical difficulties but also a rewarding experience of creating something from scratch. Designer Kwok Dylan, one of Chan's apprentices, has even published a book on Hong Kong's bird-keeping culture and birdcage crafting, hoping to revive interest in this traditional craft.

Despite the challenges, Chan remains optimistic about the future of birdcage making. He believes that with the previous generation passing on their knowledge and the next generation willing to take up the craft, the tradition of birdcage making can be preserved and continued.
