As part of the celebration for the newborn, Lee Shau-kee will give away HK$10,000 in cash to each of his 1,500 staff and friends, according to a Henderson Land spokeswoman. This will cost the patriarch at least HK$15 million in cash. The spokeswoman added that this was the fifth time Lee had given away lai see for a major family occasion. Three other times he doled out cash for the birth of a grandchild, and for Martin's wedding as well. With this payout, his lai see giveaways over the past nine years will total HK$60 million. "Uncle Four is extremely happy about the newborn grandson," said the spokeswoman, referring to the elder Lee's family nickname. The baby is the seventh grandchild between his two sons, Peter Lee Ka-kit and Martin.
