Đinh Liễn

Liễn was sent to Song China to pay tribute in 973, and was granted the title Grand Preceptor of Inspection (檢校太師 Kiểm hiệu thái sư), Jiedushi of Tĩnh Hải quân (靜海軍節度使 Tĩnh Hải quân tiết độ sứ) and Governor of the Protectorate General to Pacify the South (安南都護 An Nam đô hộ) by Song Taizu.

In the spring of 979, Đinh Liễn dispatched his subordinates to assassinate his 5 year old half brother Crown Prince Hạng Lang.

So, to assuage his parents, Đinh Liễn employed masons to carve the Uṣṇīṣa Vijaya Dhāraṇī Sūtra on 100 columns, dedicated them to his deceased younger brother and other deceased people's souls; and prayed for their release from litigations and strifes.

Đỗ Thích consistently saved Đinh family lives numerous times during Anarchy of the 12 Warlords.

There are also accusations of Lê Hoàn being involved in the assassinations, even being the mastermind behind the end of Đinh dynasty.
