To make it clear, it was a prenuptial agreement.
When Fu Qingquan divorced Old Madam Fu, he had given all of his real property to Old Madam Fu in order to retain the Kaide Corporation's shares.
Therefore, Fu Qingquan had written clearly in the agreement that after he passed away in the future, the only thing that would be left behind for Lu Qingmei would be the residence. Everything else would be inherited by Fu Tianci. Moreover, before Fu Tianci got married and had children, Secretary Song would be the one to take charge of all of the Kaide Corporation's shares that Fu Qingquan left for Fu Tianci.
Lu Qingmei blew her top when she saw this, asking what Fu Qingquan meant by doing this.
