Documented path
Jiang Jialiang started playing table tennis at age 7, taught by his father who also played the sport. He joined the Guangdong provincial team at age 13 and was selected for the Chinese national team at age 15. Training intensively five hours a day in the elite Chinese table tennis pipeline, he became a main member of the national team by age 19.
Born to a poor family in Zhongshan, Guangdong, China; father played table tennis and started him playing at age 7.
Retired from professional table tennis in 1989; later worked as a coach in Malaysia and Singapore, then as a TV commentator for Hong Kong station TVB; established a table tennis school in Shanghai in 2002.
Where the conditions came from
Each is placed on a −1 to 3 scale from documented evidence, and the three are never added together. A combined total would rank Jiang Jialiang against other people. Held apart, they explain why this path ran differently from another one—which is the only comparison this project supports.
The marble itself
+2Tailwind
What capability, drive, or early skill is documented in the person rather than their surroundings?
Selected for the Chinese national team at 15 and became a main team member by 19, with intensive five-hour daily training; exceptional table tennis aptitude recognized early in the elite Chinese pipeline.
Where it was dropped
0Neither way
What money, family standing, network, or permission was already in place before the work began?
Born to a poor family in Zhongshan, Guangdong that lacked enough food; father played table tennis and started him at 7, providing domain exposure, but family poverty was an active disadvantage partially offset by father's sport knowledge.
The shape of the track
+2Tailwind
What place, timing, institution, or peer group made the next step available?
The Chinese national table tennis pipeline — provincial team at 13, national team at 15 — provided one of the world's most elite development systems with intensive training, peer competition, and international competition access.
A −1 is a documented headwind, not a missing value; a 0 means the sources record nothing notable either way. Annotation confidence: Medium. These are analyst readings of what the sources record, not measurements of merit, talent, or effort. The twenty-two scored dimensions remain available inside the deeper research detail.
What moved through the conditions
This records repeated behaviour or recovery described by sources; it is not a grit or merit score.
This is an unchosen opening or condition in the record, not an estimate of how much luck caused the outcome.
Strongest documented signals: Elite institution pipeline, Direct domain exposure, Parent / family domain.
Describes the starting position, not what the person later made of it.
Strongest observed levers: Domain proximity, Started serious reps before 20, Prior reps.
Measures what was present, not whether it was inherited, earned, self-built, external, or mixed.
The timeline below shows the sequence of work and transitions around the selected early milestone. It is evidence of a path, not proof that every step was necessary.
Dominant figure at the top of a field. The tier summarizes documented career recognition through the data cutoff—not Jiang Jialiang's worth or future potential.
Question four · where did the leverage come from?
Each non-zero lever gets a best-supported origin, evidence signals, and confidence. Unresolved is the honest default when the biography cannot distinguish self-built, advantage-enabled, earned, external, or mixed.
One or more documented starting advantages plausibly enabled this lever.

A structural wave is external to the person, even when their position improved access to it.
This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Jiang Jialiang's outcome attributable to any origin.
Structural luck, Encounter luck, Event luck, Outcome variance can change every arrow in the path. This successful-only dataset cannot observe the near-identical paths that did not break through, so luck stays visible and unscored.
Multiplying capacity documented later in the path. Measures what was present, not whether it was inherited, earned, self-built, external, or mixed.
Access or conditions documented near the beginning of the path. Zero means "no clear evidence in reviewed sources," not "advantage was absent."
Born to a poor family in Zhongshan, Guangdong; family lacked enough food, and Jiang moved to Guangzhou at age 9 to reduce the family burden.
Father played table tennis and started Jiang playing at age 7, providing early domain exposure.
Jiang Jialiang started playing table tennis at age 7, taught by his father who also played the sport. He joined the Guangdong provincial team at age 13 and was selected for the Chinese national team at age 15, reflecting the elite Chinese table tennis pipeline. At age 19, he won team gold, doubles silver, and singles bronze at the 1983 World Table Tennis Championships. His family was poor, and he moved to Guangzhou at age 9 partly to reduce the family's burden, training intensively five hours a day.
