Chloroquine is under current investigation (ie results not yet in, and certainly not a treatment protocol) and zinc has been shown in some cases to maybe improve some aspect of illness, it’s far from proven.
The rest of what they said is at best speculation/conjecture.

DIY on zinc - There is an entire industry of antiviral zinc sprays, lozenges and pills. Zinc stops viral replication deader than your prefrontal lobes:

Like I said, we have herein a safe treatment that is cheap, available, and free of risk, namely
1. immediate zinc lozenge/spray/pill dissolved in mouth to be applied early (preferably first 3 days) of illness, and possibly every day thereafter +
2.Chloroquine phosphate (up to 500 mg/day).
Otherwise, I'll continue to flag posts like this.

L.A.Times article with links (feel free to chase the links yourself) that gives more detail about the above paper cited:
"A more unorthodox remedy being tested against the coronavirus in China is chloroquine.
The drug is intended to treat malaria, a condition caused by a parasite transmitted through a mosquito bite. A limited number of studies suggest the drug can work against SARS. In laboratory tests, it kept COVID-19 from spreading by blocking its method of infecting cells, according to a report last week in the journal Cell Research."
The Chinese source re chloroquine, was posted on ycombinator by sp332 3 hours ago (I quote him below):

"This summarizes the results of a bunch of trials that were run in parallel in China."
You can do your own search for information on the effects of zinc on viruses and in particular corona viruses - it's old story (dating back to circa 1970s at least), the results have created a entire industry of zinc-related products (zicam et al).
