A lot of them… name of elements

Only two of them (釷, 鈥: Holmium) are currently used element names.

It is unfortunate that the characters 鈥釷 are replaced by 钬钍, ruining the consistency.

Recognised characters:

• 淦 – alt. form of 幹 – alt. form of 姦, from zh-min-nan – fuck
• 釷 – thorium
• 林 – forest; a surname
• 沐 – appears in 沐浴 – shower
• 杜 – appears in 杜甫 – a famous poet
• 淡 – watered down; appears in 淡水 – fresh water
• 炎 – flame
• 灶 – stove
• 圭 – appears in 日圭 – alt. form of 日晷 – sundial

With context, this sentence can be simplified to

有屎必有尿；有尿不必有屎。
