This is not correct.  For example, the scholar Zhāng Zhào (張照),
1691-1745, was a main author of a famous music theory book called Lǜlǚ
Zhèngyì (律呂正義), one of the first treatises that describe a method
to construct well-tempered tunings.

`ü' is used after `l', since both `lu' and `lü' are possible.
