Dr. Xiaoboming provi☆<ded deeper insights and supπ•×plements during the lecture, ₽₽↕reinforcing understanding thr₩←¥ ough examples from the project, ✔≠allowing colleagues to gain a d¶×eeper understanding of chemical drug de±®velopment work.
The lecture lasted about 9 hours. Tγ≤ hrough this training, colleag$φues at Haibu Pharmaceutical benefited g↓$reatly. The advanced R₹♦&D ideas brought by the teac✘π§πhers broadened everyone's research ↑γand development perspective. ∞¶The two teachers also expressedδ¥ their recognition of e✔γveryone's learning attitude and enthu≈ siasm, believing that in future$↓↓± drug development work, they ♣✔can apply what they have learne₽♦σγd to contribute to the company's vigφ>©orous and stable developm♣•←ent.
