Chan Wah-shun (c. 1836 – 1906), nicknamed Money Changer Wah (找錢華) and Money Clutcher Wah (爪錢華), was a student of the Wing Chun grandmaster Leung Jan (梁贊).^[2] He is noted for being the martial arts teacher of Ip Man.

Born in Shunde District, Foshan in 1836, Chan ran a currency exchange stall near Dit Da and Wing Chun practitioner Leung Jan's herbal medicine clinic in Foshan.^[2] He carried heavy loads of coins every day, and so developed great strength over the years. In 1884, his son Chan Yu-gum (陳汝錦) was born.

In 1888, Leung Jan's physical health had begun to decline and his sons, including Leung Bik (梁壁 Liáng Bì; loeng4 bik1) and Leung Chun (梁春 loeng4 cheun1), had left Foshan to make a living. They had no intention of taking over his training hall, named Wing Sang Tong (榮生堂), also known as Jan Sang Tong (贊生堂), which was looked after by his student Lee Wah (李華), nicknamed Woodman Wah (木人華).

While searching for a successor, Leung took in Chan as his student. Leung would later often return to his hometown Gulao Village (古勞), and Chan continued to be trained by Lee. Chan also learned traditional Chinese medicine Dit Da from Leung. Chan eventually closed his money changing business and helped ran a Dit Da clinic.

Upon the death of Lee in the following year in 1889, Chan took over the operations of the training hall, while Leung went back and forth between Foshan and Gulao. Wing Sang Tong was later renamed to Hang Chai Tong (杏濟堂).

Chan started training his young son in Wing Chun in 1892. Chan assisted Leung for only four years.

With the death of Leung Jan in 1901, Chan left Hang Chai Tong and worked at a ceramic shop at Lianhua Street.

In 1906, he rented a huge ancestral hall at Yejia Village, Chancheng District at Foshan for teaching Wing Chun, which was where he accepted his 16th and last student, Ip Man. Chan was only able to teach the students for three years when in 1909,^[2] he suffered a mild stroke. Chan asked his second student, Ng Chung-sok (吳仲素), to take over the hall and continue with students' trainings before retiring back to his village at Shunde. Chan died of illness in 1913 and was buried there.
