TVB Operation Relief Teleton took place on June 24, 1972 and this photo was taken around mid June, 1972. How can it be few months. You just can't accept the fact he's not Brandon and ignoring the actual date of the telethon. LOL
Anyway, the other posts below has said he is Au Yeung Tak Fan younger brother of Au Yeung Tak Dung not Brandon. You may also check the photos of Brandon's visit to WOTD shooting with Linda and Shannon. He didn't look that short in size as this little boy.
