บท 272: Chapter 183 New Skills

"This is a 5.2 difficulty level route, also divided by the rating of our domestic standard, Y.D.S (Yosemite Decimal System)."

After the coach finished speaking, Javell also explained:

"The number 5 represents the rock climbing route we are now undertaking, and the 2 indicates that this route has a difficulty level of 2. When the difficulty level reaches 14, further distinctions will be made with the letters abcd, with the current highest level of difficulty being 5.15c."

When he officially started climbing, Li Ang also felt that this sport was much easier for him than what the coach had just introduced.
