Whether you play e-sports（電子競技）or not, you might have heard of iG (Invictus Gaming), a Chinese e-sports club. On the night of Nov 3, iG beat Europe’s Fnatic club and won the 2018 League of Legends (LoL) World Championship in South Korea. It was the first time in the event’s（賽事）eight-year history that a Chinese club won.

The long-awaited victory showed how e-sports has progressed in China in recent years. A growing number of e-sports clubs have been founded in China in the last 10 years, and more young gamers are working as e-sports players. However, becoming a skillful e-sports player is not all fun and games.

An e-sports player must be quick in action and able to bear hardship.

They must also have a high APM which means how many actions they can do in a game within one minute. Skilled players can have an APM as high as 400.

There is a limit（限制）to how long they can play this well. Skillful players’ ages are mostly from 17 to 25. After a certain age, they become slower.

E-sports players have to work hard every day. “We start to practice right after we get up in the morning and usually last until midnight,” said Huang Fuquan, a player from iG. “There is at least 12 hours of work every day.”

Many players practice so much that they get pains and arthritis（關(guān)節(jié)炎）. They also face lots of problems. Some e-sports clubs even invite doctors to help their players.

So if you want to turn your love for gaming into a full-time job, ask yourself this first: Are you really prepared?
