Chen San-yuan can also be described as Pokémon Go's grandfather. He is from Taiwan, and is undoubtedly one of Pokémon's best players, or at least the most dedicated.
San-yuan made international headlines in August when they watched him chase Pokémons with a bicycle and 11 phones on a dock. Judging from a recent picture of San-yuan who posted on Twitter, apparently upgraded his system with a waist dock and so no longer needs the bike.
According to the local news agency he discovered, San-yuan spends more than 1.000 dollars a month on his hobby. Pokemon's favorite is the Snorlax and he always holds a bag to constantly charge his phones.
No matter how good you are in Pokémon, you will never reach San-yuan, unless you have the necessary budget, but also a retiree's free time.
