=== Example 5===
# After calling three times, player has in hand: {{#mjt:1234m}}
# Left player discards: {{#mjt:1m}}
# If chii is called to form {{#mjt:1'23m}}, then only {{#mjt:1m}} and {{#mjt:4m}} are left over.
# However, discarding either {{#mjt:1m}} or {{#mjt:4m}} will violate the rules above. Therefore, player cannot call chii on {{#mjt:1m}}.

* Some rulesets (such as [[Japan Professional Mahjong League|JPML A]]) may disallow discarding the exact tile that was called, but allow any other discard. For example, under this rule, with a sequence of 123, you can call chii on 4, discard 1, and have a 234 set.
