Dr. Xiaoboming provided deepe•σ↕r insights and supplement α ♠s during the lecture, rei↑✔nforcing understanding th$ε$rough examples from the projeβ★ct, allowing colleagues to g®εδain a deeper understanding of chemical™₹'ε drug development work.
The lecture lasted about φ♦α9 hours. Through thiλγ★s training, colleagues at ™βα©Haibu Pharmaceutical benefited•£ greatly. The advanced R&D id₩®eas brought by the teac÷π≤σhers broadened everyone's research an✔≠d development perspective. The two tea≠ε→≈chers also expressed their recogn¶≈£ition of everyone's learning att ←itude and enthusiasm, believing✘₩ that in future drug development §βwork, they can apply what they have ≥γ☆learned to contributΩ↓e to the company's vigorous and stab←δ↔↕le development.
