A Powerful Son-In-Law

Is the son-in-law merely cowardly and inferior to a pig or a dog? I have the steel in hand, and out of ten thousand troops, seven will come in and seven will come out! Is the son-in-law dependent on others and being humble? I am bold and unruly, and thousands of flowers are charming and proud! A son-in-law with a large household, a living room, a lowly and lowly person? I support the dynasty, and all nations kneel to the sea and clear the rivers!
